+		SENDMAIL CONFIGURATION FILES
+
+This document describes the sendmail configuration files.  This package
+requires a post-V7 version of m4; if you are running the 4.2bsd, SysV.2, or
+7th Edition version.  SunOS's /usr/5bin/m4 or BSD-Net/2's m4 both work.
+GNU m4 version 1.1 or later also works.  Unfortunately, the M4 on BSDI 1.0
+doesn't work -- you'll have to use a Net/2 or GNU version.  GNU m4 is
+available from ftp://ftp.gnu.org/pub/gnu/m4-1.4.tar.gz (check for the
+latset version).  EXCEPTIONS: DEC's m4 on Digital UNIX 4.x is broken (3.x
+is fine).  Use GNU m4 on this platform.
+
+To get started, you may want to look at tcpproto.mc (for TCP-only sites),
+uucpproto.mc (for UUCP-only sites), and clientproto.mc (for clusters of
+clients using a single mail host).  Others are versions previously used at
+Berkeley.  For example, ucbvax has gone away, but ucbvax.mc demonstrates
+some interesting techniques.
+
+*******************************************************************
+***  BE SURE YOU CUSTOMIZE THESE FILES!  They have some		***
+***  Berkeley-specific assumptions built in, such as the name	***
+***  of their UUCP-relay.  You'll want to create your own	***
+***  domain description, and use that in place of		***
+***  domain/Berkeley.EDU.m4.					***
+*******************************************************************
+
+
++--------------------------+
+| INTRODUCTION AND EXAMPLE |
++--------------------------+
+
+Configuration files are contained in the subdirectory "cf", with a
+suffix ".mc".  They must be run through "m4" to produce a ".cf" file.
+You must pre-load "cf.m4":
+
+	m4 ${CFDIR}/m4/cf.m4 config.mc > config.cf
+
+Alternatively, you can simply:
+
+	cd ${CFDIR}/cf
+	./Build config.cf
+
+where ${CFDIR} is the root of the cf directory and config.mc is the
+name of your configuration file.  If you are running a version of M4
+that understands the __file__ builtin (versions of GNU m4 >= 0.75 do
+this, but the versions distributed with 4.4BSD and derivatives do not)
+or the -I flag (ditto), then ${CFDIR} can be in an arbitrary directory.
+For "traditional" versions, ${CFDIR} ***MUST*** be "..", or you MUST
+use -D_CF_DIR_=/path/to/cf/dir/ -- note the trailing slash!  For example:
+
+	m4 -D_CF_DIR_=${CFDIR}/ ${CFDIR}/m4/cf.m4 config.mc > config.cf
+
+Let's examine a typical .mc file:
+
+	divert(-1)
+	#
+	# Copyright (c) 1998-2000 Sendmail, Inc. and its suppliers.
+	#	All rights reserved.
+	# Copyright (c) 1983 Eric P. Allman.  All rights reserved.
+	# Copyright (c) 1988, 1993
+	#	The Regents of the University of California.  All rights reserved.
+	#
+	# By using this file, you agree to the terms and conditions set
+	# forth in the LICENSE file which can be found at the top level of
+	# the sendmail distribution.
+	#
+
+	#
+	#  This is a Berkeley-specific configuration file for HP-UX 9.x.
+	#  It applies only to the Computer Science Division at Berkeley,
+	#  and should not be used elsewhere.   It is provided on the sendmail
+	#  distribution as a sample only.  To create your own configuration
+	#  file, create an appropriate domain file in ../domain, change the
+	#  `DOMAIN' macro below to reference that file, and copy the result
+	#  to a name of your own choosing.
+	#
+	divert(0)
+
+The divert(-1) will delete the crud in the resulting output file.
+The copyright notice can be replaced by whatever your lawyers require;
+our lawyers require the one that is included in these files.  A copyleft
+is a copyright by another name.  The divert(0) restores regular output.
+
+	VERSIONID(`<SCCS or RCS version id>')
+
+VERSIONID is a macro that stuffs the version information into the
+resulting file.  You could use SCCS, RCS, CVS, something else, or
+omit it completely.  This is not the same as the version id included
+in SMTP greeting messages -- this is defined in m4/version.m4.
+
+	OSTYPE(`hpux9')dnl
+
+You must specify an OSTYPE to properly configure things such as the
+pathname of the help and status files, the flags needed for the local
+mailer, and other important things.  If you omit it, you will get an
+error when you try to build the configuration.  Look at the ostype
+directory for the list of known operating system types.
+
+	DOMAIN(`CS.Berkeley.EDU')dnl
+
+This example is specific to the Computer Science Division at Berkeley.
+You can use "DOMAIN(`generic')" to get a sufficiently bland definition
+that may well work for you, or you can create a customized domain
+definition appropriate for your environment.
+
+	MAILER(`local')
+	MAILER(`smtp')
+
+These describe the mailers used at the default CS site.  The
+local mailer is always included automatically.  Beware: MAILER
+declarations should always be at the end of the configuration file,
+and MAILER(`smtp') should always precede MAILER(`procmail'), and
+MAILER(`uucp').  The general rules are that the order should be:
+
+	VERSIONID
+	OSTYPE
+	DOMAIN
+	FEATURE
+	local macro definitions
+	MAILER
+	LOCAL_RULE_*
+	LOCAL_RULESETS
+
+There are a few exceptions to this rule.  Local macro definitions which
+influence a FEATURE() should be done before that feature.  For example,
+a define(`PROCMAIL_MAILER_PATH', ...) should be done before
+FEATURE(`local_procmail').
+
+
++----------------------------+
+| A BRIEF INTRODUCTION TO M4 |
++----------------------------+
+
+Sendmail uses the M4 macro processor to ``compile'' the configuration
+files.  The most important thing to know is that M4 is stream-based,
+that is, it doesn't understand about lines.  For this reason, in some
+places you may see the word ``dnl'', which stands for ``delete
+through newline''; essentially, it deletes all characters starting
+at the ``dnl'' up to and including the next newline character.  In
+most cases sendmail uses this only to avoid lots of unnecessary
+blank lines in the output.
+
+Other important directives are define(A, B) which defines the macro
+``A'' to have value ``B''.  Macros are expanded as they are read, so
+one normally quotes both values to prevent expansion.  For example,
+
+	define(`SMART_HOST', `smart.foo.com')
+
+One word of warning:  M4 macros are expanded even in lines that appear
+to be comments.  For example, if you have
+
+	# See FEATURE(`foo') above
+
+it will not do what you expect, because the FEATURE(`foo') will be
+expanded.  This also applies to
+
+	# And then define the $X macro to be the return address
+
+because ``define'' is an M4 keyword.  If you want to use them, surround
+them with directed quotes, `like this'.
+
++----------------+
+| FILE LOCATIONS |
++----------------+
+
+sendmail 8.9 has introduced a new configuration directory for sendmail
+related files, /etc/mail.  The new files available for sendmail 8.9 --
+the class 'R' /etc/mail/relay-domains and the access database
+/etc/mail/access -- take advantage of this new directory.  Beginning with
+8.10, all files will use this directory by default (some options may be
+set by OSTYPE() files).  This new directory should help to restore
+uniformity to sendmail's file locations.
+
+Below is a table of some of the common changes:
+
+Old filename			New filename
+------------			------------
+/etc/bitdomain			/etc/mail/bitdomain
+/etc/domaintable		/etc/mail/domaintable
+/etc/genericstable		/etc/mail/genericstable
+/etc/uudomain			/etc/mail/uudomain
+/etc/virtusertable		/etc/mail/virtusertable
+/etc/userdb			/etc/mail/userdb
+
+/etc/aliases			/etc/mail/aliases
+/etc/sendmail/aliases		/etc/mail/aliases
+/etc/ucbmail/aliases		/etc/mail/aliases
+/usr/adm/sendmail/aliases	/etc/mail/aliases
+/usr/lib/aliases		/etc/mail/aliases
+/usr/lib/mail/aliases		/etc/mail/aliases
+/usr/ucblib/aliases		/etc/mail/aliases
+
+/etc/sendmail.cw		/etc/mail/local-host-names

+/etc/sendmail/sendmail.st	/etc/mail/statistics
+/usr/lib/sendmail.st		/etc/mail/statistics
+/usr/ucblib/sendmail.st		/etc/mail/statistics
+
+Note that all of these paths actually use a new m4 macro MAIL_SETTINGS_DIR
+to create the pathnames.  The default value of this variable is
+`/etc/mail/'.  If you set this macro to a different value, you MUST include
+a trailing slash.
+
++--------+
+| OSTYPE |
++--------+
+
+You MUST define an operating system environment, or the configuration
+file build will puke.  There are several environments available; look
+at the "ostype" directory for the current list.  This macro changes
+things like the location of the alias file and queue directory.  Some
+of these files are identical to one another.
+
+It is IMPERATIVE that the OSTYPE occur before any MAILER definitions.
+In general, the OSTYPE macro should go immediately after any version
+information, and MAILER definitions should always go last.
+
+Operating system definitions are usually easy to write.  They may define
+the following variables (everything defaults, so an ostype file may be
+empty).  Unfortunately, the list of configuration-supported systems is
+not as broad as the list of source-supported systems, since many of
+the source contributors do not include corresponding ostype files.
+
+ALIAS_FILE		[/etc/mail/aliases] The location of the text version
+			of the alias file(s).  It can be a comma-separated
+			list of names (but be sure you quote values with
+			commas in them -- for example, use
+				define(`ALIAS_FILE', `a,b')
+			to get "a" and "b" both listed as alias files;
+			otherwise the define() primitive only sees "a").
+HELP_FILE		[/etc/mail/helpfile] The name of the file
+			containing information printed in response to
+			the SMTP HELP command.
+QUEUE_DIR		[/var/spool/mqueue] The directory containing
+			queue files.  To use multiple queues, supply 
+			a value ending with an asterisk.  For 
+			example, /var/spool/mqueue/q* will use all of the
+			directories or symbolic links to directories
+			beginning with 'q' in /var/spool/mqueue as queue
+			directories.
+STATUS_FILE		[/etc/mail/statistics] The file containing status
+			information.
+LOCAL_MAILER_PATH	[/bin/mail] The program used to deliver local mail.
+LOCAL_MAILER_FLAGS	[Prmn9] The flags used by the local mailer.  The
+			flags lsDFMAw5:/|@q are always included.

+			messages to deliver in a single connection.  Only
+			useful for LMTP local mailers.
+LOCAL_MAILER_CHARSET	[undefined] If defined, messages containing 8-bit data
+			that ARRIVE from an address that resolves to the
+			local mailer and which are converted to MIME will be
+			labeled with this character set.
+LOCAL_MAILER_EOL	[undefined] If defined, the string to use as the
+			end of line for the local mailer.
+LOCAL_MAILER_DSN_DIAGNOSTIC_CODE
+			[X-Unix] The DSN Diagnostic-Code value for the

+			"esmtp" mailer adds `a'; "smtp8" adds `8'; and
+			"dsmtp" adds `%'.
+RELAY_MAILER_FLAGS	[undefined] Flags added to the relay mailer.  Default
+			flags are `mDFMuX' for all SMTP-based mailers; the
+			relay mailer adds `a8'.

+			messages to deliver in a single connection for the
+			smtp, smtp8, esmtp, or dsmtp mailers.
+SMTP_MAILER_ARGS	[IPC $h] The arguments passed to the smtp mailer.
+			About the only reason you would want to change this
+			would be to change the default port.

+QPAGE_MAILER_MAX	[4096] If set, the maximum size message that
+			will be accepted by the qpage mailer.
+
+Note: to tweak Name_MAILER_FLAGS use the macro MODIFY_MAILER_FLAGS:
+MODIFY_MAILER_FLAGS(`Name', `change') where Name is the first part of
+the macro Name_MAILER_FLAGS and change can be: flags that should
+be used directly (thus overriding the default value), or if it
+starts with `+' (`-') then those flags are added to (removed from)
+the default value.  Example:
+
+	MODIFY_MAILER_FLAGS(`LOCAL', `+e')
+
+will add the flag `e' to LOCAL_MAILER_FLAGS.
+WARNING: The FEATUREs local_lmtp and local_procmail set LOCAL_MAILER_FLAGS
+unconditionally, i.e., without respecting any definitions in an
+OSTYPE setting.
+
+
++---------+
+| DOMAINS |
++---------+
+
+You will probably want to collect domain-dependent defines into one
+file, referenced by the DOMAIN macro.  For example, the Berkeley
+domain file includes definitions for several internal distinguished
+hosts:
+
+UUCP_RELAY	The host that will accept UUCP-addressed email.
+		If not defined, all UUCP sites must be directly
+		connected.
+BITNET_RELAY	The host that will accept BITNET-addressed email.
+		If not defined, the .BITNET pseudo-domain won't work.
+DECNET_RELAY	The host that will accept DECNET-addressed email.
+		If not defined, the .DECNET pseudo-domain and addresses
+		of the form node::user will not work.
+FAX_RELAY	The host that will accept mail to the .FAX pseudo-domain.
+		The "fax" mailer overrides this value.
+LOCAL_RELAY	DEPRECATED.  The site that will handle unqualified
+		names -- that is, names with out an @domain extension.
+		If not set, they are assumed to belong on this machine.
+		This allows you to have a central site to store a
+		company- or department-wide alias database.  This
+		only works at small sites, and only with some user
+		agents.
+LUSER_RELAY	The site that will handle lusers -- that is, apparently
+		local names that aren't local accounts or aliases.  To
+		specify a local user instead of a site, set this to
+		``local:username''.
+
+Any of these can be either ``mailer:hostname'' (in which case the
+mailer is the internal mailer name, such as ``uucp-new'' and the hostname
+is the name of the host as appropriate for that mailer) or just a
+``hostname'', in which case a default mailer type (usually ``relay'',
+a variant on SMTP) is used.  WARNING: if you have a wildcard MX
+record matching your domain, you probably want to define these to
+have a trailing dot so that you won't get the mail diverted back
+to yourself.
+
+The domain file can also be used to define a domain name, if needed
+(using "DD<domain>") and set certain site-wide features.  If all hosts
+at your site masquerade behind one email name, you could also use
+MASQUERADE_AS here.
+
+You do not have to define a domain -- in particular, if you are a
+single machine sitting off somewhere, it is probably more work than
+it's worth.  This is just a mechanism for combining "domain dependent
+knowledge" into one place.
+
++---------+
+| MAILERS |
++---------+
+
+There are fewer mailers supported in this version than the previous
+version, owing mostly to a simpler world.  As a general rule, put the
+MAILER definitions last in your .mc file, and always put MAILER(`smtp')
+before MAILER(`uucp') and MAILER(`procmail') -- several features and
+definitions will modify the definition of mailers, and the smtp mailer
+modifies the UUCP mailer.  Moreover, MAILER(`cyrus'), MAILER(`pop'),
+MAILER(`phquery'), and MAILER(`usenet') must be defined after
+MAILER(`local').
+
+local		The local and prog mailers.  You will almost always
+		need these; the only exception is if you relay ALL
+		your mail to another site.  This mailer is included
+		automatically.
+
+smtp		The Simple Mail Transport Protocol mailer.  This does
+		not hide hosts behind a gateway or another other
+		such hack; it assumes a world where everyone is
+		running the name server.  This file actually defines
+		five mailers: "smtp" for regular (old-style) SMTP to
+		other servers, "esmtp" for extended SMTP to other
+		servers, "smtp8" to do SMTP to other servers without
+		converting 8-bit data to MIME (essentially, this is
+		your statement that you know the other end is 8-bit
+		clean even if it doesn't say so), "dsmtp" to do on
+		demand delivery, and "relay" for transmission to the
+		RELAY_HOST, LUSER_RELAY, or MAIL_HUB.
+
+uucp		The Unix-to-Unix Copy Program mailer.  Actually, this
+		defines two mailers, "uucp-old" (a.k.a. "uucp") and
+		"uucp-new" (a.k.a. "suucp").  The latter is for when you
+		know that the UUCP mailer at the other end can handle
+		multiple recipients in one transfer.  If the smtp mailer
+		is also included in your configuration, two other mailers
+		("uucp-dom" and "uucp-uudom") are also defined [warning:
+		you MUST specify MAILER(smtp) before MAILER(uucp)].  When you
+		include the uucp mailer, sendmail looks for all names in
+		the $=U class and sends them to the uucp-old mailer; all
+		names in the $=Y class are sent to uucp-new; and all
+		names in the $=Z class are sent to uucp-uudom.  Note that
+		this is a function of what version of rmail runs on
+		the receiving end, and hence may be out of your control.
+		See the section below describing UUCP mailers in more
+		detail.
+
+usenet		Usenet (network news) delivery.  If this is specified,
+		an extra rule is added to ruleset 0 that forwards all
+		local email for users named ``group.usenet'' to the
+		``inews'' program.  Note that this works for all groups,
+		and may be considered a security problem.
+
+fax		Facsimile transmission.  This is experimental and based
+		on Sam Leffler's HylaFAX software.  For more information,
+		see http://www.vix.com/hylafax/.
+
+pop		Post Office Protocol.
+
+procmail	An interface to procmail (does not come with sendmail).
+		This is designed to be used in mailertables.  For example,
+		a common question is "how do I forward all mail for a given
+		domain to a single person?".  If you have this mailer
+		defined, you could set up a mailertable reading:
+
+			host.com	procmail:/etc/procmailrcs/host.com
+
+		with the file /etc/procmailrcs/host.com reading:
+
+			:0	# forward mail for host.com
+			! -oi -f $1 person@other.host
+
+		This would arrange for (anything)@host.com to be sent
+		to person@other.host.  Within the procmail script, $1 is
+		the name of the sender and $2 is the name of the recipient.
+		If you use this with FEATURE(`local_procmail'), the FEATURE
+		should be listed first.
+
+mail11		The DECnet mail11 mailer, useful only if you have the mail11
+		program from gatekeeper.dec.com:/pub/DEC/gwtools (and
+		DECnet, of course).  This is for Phase IV DECnet support;
+		if you have Phase V at your site you may have additional
+		problems.
+
+phquery		The phquery program.  This is somewhat counterintuitively
+		referenced as the "ph" mailer internally.  It can be used
+		to do CCSO name server lookups.  The phquery program, which
+		this mailer uses, is distributed with the ph client.
+
+cyrus		The cyrus and cyrusbb mailers.  The cyrus mailer delivers to
+		a local cyrus user.  this mailer can make use of the
+		"user+detail@local.host" syntax; it will deliver the mail to
+		the user's "detail" mailbox if the mailbox's ACL permits.
+		The cyrusbb mailer delivers to a system-wide cyrus mailbox
+		if the mailbox's ACL permits.  The cyrus mailer must be
+		defined after the local mailer.
+
+qpage		A mailer for QuickPage, a pager interface.  See
+		http://www.qpage.org/ for further information.
+
+The local mailer accepts addresses of the form "user+detail", where
+the "+detail" is not used for mailbox matching but is available
+to certain local mail programs (in particular, see
+FEATURE(`local_procmail')).  For example, "eric", "eric+sendmail", and
+"eric+sww" all indicate the same user, but additional arguments <null>,
+"sendmail", and "sww" may be provided for use in sorting mail.

++----------+
+| FEATURES |
++----------+
+
+Special features can be requested using the "FEATURE" macro.  For
+example, the .mc line:
+
+	FEATURE(`use_cw_file')
+
+tells sendmail that you want to have it read an /etc/mail/local-host-names
+file to get values for class $=w.  The FEATURE may contain up to 9
+optional parameters -- for example:
+
+	FEATURE(`mailertable', `dbm /usr/lib/mailertable')
+
+The default database map type for the table features can be set with
+
+	define(`DATABASE_MAP_TYPE', `dbm')
+
+which would set it to use ndbm databases.  The default is the Berkeley DB
+hash database format.  Note that you must still declare a database map type
+if you specify an argument to a FEATURE.  DATABASE_MAP_TYPE is only used
+if no argument is given for the FEATURE.  It must be specified before any
+feature that uses a map.
+
+Available features are:
+
+use_cw_file	Read the file /etc/mail/local-host-names file to get
+		alternate names for this host.  This might be used if you
+		were on a host that MXed for a dynamic set of other hosts.
+		If the set is static, just including the line "Cw<name1>
+		<name2> ..." (where the names are fully qualified domain
+		names) is probably superior.  The actual filename can be
+		overridden by redefining confCW_FILE.
+
+use_ct_file	Read the file /etc/mail/trusted-users file to get the
+		names of users that will be ``trusted'', that is, able to
+		set their envelope from address using -f without generating
+		a warning message.  The actual filename can be overridden
+		by redefining confCT_FILE.
+
+redirect	Reject all mail addressed to "address.REDIRECT" with
+		a ``551 User not local; please try <address>'' message.
+		If this is set, you can alias people who have left
+		to their new address with ".REDIRECT" appended.
+
+nouucp		Don't route UUCP addresses.  This feature takes one
+		parameter:
+		`reject': reject addresses which have "!" in the local
+			part unless it originates from a system
+			that is allowed to relay.
+		`nospecial': don't do anything special with "!".
+		Warnings: 1. See the NOTICE in the ANTI-SPAM section.
+		2. don't remove "!" from OperatorChars if `reject' is
+		given as parameter.
+
+nocanonify	Don't pass addresses to $[ ... $] for canonification
+		by default.  It can be changed by setting the
+		DaemonPortOptions modifiers (M=).  That is,
+		FEATURE(`nocanonify') will be overridden by setting the
+		'c' flag.  Conversely, if FEATURE(`nocanonify') is not used,
+		it can be emulated by setting the 'C' flag
+		(DaemonPortOptions=Modifiers=C).  This would generally only
+		be used by sites that only act as mail gateways or which have
+		user agents that do full canonification themselves.  You may
+		also want to use
+		"define(`confBIND_OPTS', `-DNSRCH -DEFNAMES')" to turn off
+		the usual resolver options that do a similar thing.
+
+		An exception list for FEATURE(`nocanonify') can be
+		specified with CANONIFY_DOMAIN or CANONIFY_DOMAIN_FILE,
+		i.e., a list of domains which are nevertheless passed to
+		$[ ... $] for canonification.  This is useful to turn on
+		canonification for local domains, e.g., use
+		CANONIFY_DOMAIN(`my.domain my') to canonify addresses
+		which end in "my.domain" or "my".
+		Another way to require canonification in the local
+		domain is CANONIFY_DOMAIN(`$=m').
+
+		A trailing dot is added to addresses with more than
+		one component in it such that other features which
+		expect a trailing dot (e.g., virtusertable) will
+		still work.
+
+		If `canonify_hosts' is specified as parameter, i.e.,
+		FEATURE(`nocanonify', `canonify_hosts'), then
+		addresses which have only a hostname, e.g.,
+		<user@host>, will be canonified (and hopefully fully
+		qualified), too.
+
+stickyhost	If set, email sent to "user@local.host" are marked
+		as "sticky" -- that is, the local addresses aren't
+		matched against UDB and don't go through ruleset 5.
+		This is used if you want a set up where "user" is
+		not necessarily the same as "user@local.host", e.g.,
+		to make a distinct domain-wide namespace.  Prior to
+		8.7 this was the default, and notsticky was used to
+		turn this off.
+
+mailertable	Include a "mailer table" which can be used to override
+		routing for particular domains (which are not in $=w, i.e.
+		local host names).  The argument of the FEATURE may be the
+		key definition.  If none is specified, the definition used
+		is:
+
+			hash /etc/mail/mailertable
+
+		Keys in this database are fully qualified domain names
+		or partial domains preceded by a dot -- for example,
+		"vangogh.CS.Berkeley.EDU" or ".CS.Berkeley.EDU".  As a
+		special case of the latter, "." matches any domain not
+		covered by other keys.  Values must be of the form:
+			mailer:domain
+		where "mailer" is the internal mailer name, and "domain"
+		is where to send the message.  These maps are not
+		reflected into the message header.  As a special case,
+		the forms:
+			local:user
+		will forward to the indicated user using the local mailer,
+			local:
+		will forward to the original user in the e-mail address
+		using the local mailer, and
+			error:code message
+			error:D.S.N:code message
+		will give an error message with the indicated SMTP reply
+		code and message, where D.S.N is an RFC 1893 compliant
+		error code.
+
+domaintable	Include a "domain table" which can be used to provide
+		domain name mapping.  Use of this should really be
+		limited to your own domains.  It may be useful if you
+		change names (e.g., your company changes names from
+		oldname.com to newname.com).  The argument of the
+		FEATURE may be the key definition.  If none is specified,
+		the definition used is:
+
+			hash /etc/mail/domaintable
+
+		The key in this table is the domain name; the value is
+		the new (fully qualified) domain.  Anything in the
+		domaintable is reflected into headers; that is, this
+		is done in ruleset 3.
+
+bitdomain	Look up bitnet hosts in a table to try to turn them into
+		internet addresses.  The table can be built using the
+		bitdomain program contributed by John Gardiner Myers.
+		The argument of the FEATURE may be the key definition; if
+		none is specified, the definition used is:
+
+			hash /etc/mail/bitdomain
+
+		Keys are the bitnet hostname; values are the corresponding
+		internet hostname.
+
+uucpdomain	Similar feature for UUCP hosts.  The default map definition
+		is:
+
+			hash /etc/mail/uudomain
+
+		At the moment there is no automagic tool to build this
+		database.
+
+always_add_domain
+		Include the local host domain even on locally delivered
+		mail.  Normally it is not added on unqualified names.
+		However, if you use a shared message store but do not use
+		the same user name space everywhere, you may need the host
+		name on local names.
+
+allmasquerade	If masquerading is enabled (using MASQUERADE_AS), this
+		feature will cause recipient addresses to also masquerade
+		as being from the masquerade host.  Normally they get
+		the local hostname.  Although this may be right for
+		ordinary users, it can break local aliases.  For example,
+		if you send to "localalias", the originating sendmail will
+		find that alias and send to all members, but send the
+		message with "To: localalias@masqueradehost".  Since that
+		alias likely does not exist, replies will fail.  Use this
+		feature ONLY if you can guarantee that the ENTIRE
+		namespace on your masquerade host supersets all the
+		local entries.
+
+limited_masquerade
+		Normally, any hosts listed in $=w are masqueraded.  If this
+		feature is given, only the hosts listed in $=M are masqueraded.
+		This is useful if you have several domains with disjoint
+		namespaces hosted on the same machine.
+
+masquerade_entire_domain
+		If masquerading is enabled (using MASQUERADE_AS) and
+		MASQUERADE_DOMAIN (see below) is set, this feature will
+		cause addresses to be rewritten such that the masquerading
+		domains are actually entire domains to be hidden.  All
+		hosts within the masquerading domains will be rewritten
+		to the masquerade name (used in MASQUERADE_AS).  For example,
+		if you have:
+
+			MASQUERADE_AS(`masq.com')
+			MASQUERADE_DOMAIN(`foo.org')
+			MASQUERADE_DOMAIN(`bar.com')
+
+		then *foo.org and *bar.com are converted to masq.com.  Without
+		this feature, only foo.org and bar.com are masqueraded.
+
+		    NOTE: only domains within your jurisdiction and
+		    current hierarchy should be masqueraded using this.
+
+genericstable	This feature will cause certain addresses originating locally
+		(i.e., that are unqualified) or a domain listed in $=G to be
+		looked up in a map and turned into another ("generic") form,
+		which can change both the domain name and the user name.  This
+		is similar to the userdb functionality.  The same types of
+		addresses as for masquerading are looked up, i.e., only header
+		sender addresses unless the allmasquerade and/or
+		masquerade_envelope features are given.  Qualified addresses
+		must have the domain part in the list of names given by the
+		by the macros GENERICS_DOMAIN or GENERICS_DOMAIN_FILE
+		(analogously to MASQUERADE_DOMAIN and MASQUERADE_DOMAIN_FILE,
+		see below).
+
+		The argument of FEATURE(`genericstable') may be the map
+		definition; the default map definition is:
+
+			hash /etc/mail/genericstable
+
+		The key for this table is either the full address, the domain
+		(with a leading @; the localpart is passed as first argument)
+		or the unqualified username (tried in the order mentioned);
+		the value is the new user address.  If the new user address
+		does not include a domain, it will be qualified in the standard
+		manner, i.e., using $j or the masquerade name.  Note that the
+		address being looked up must be fully qualified.  For local
+		mail, it is necessary to use FEATURE(`always_add_domain')
+		for the addresses to be qualified.
+		The "+detail" of an address is passed as %1, so entries like
+
+			old+*@foo.org	new+%1@example.com
+			gen+*@foo.org	%1@example.com
+
+		and other forms are possible.
+
+generics_entire_domain
+		If the genericstable is enabled and GENERICS_DOMAIN or
+		GENERICS_DOMAIN_FILE is used, this feature will cause
+		addresses to be searched in the map if their domain
+		parts are subdomains of elements in class $=G.
+
+virtusertable	A domain-specific form of aliasing, allowing multiple
+		virtual domains to be hosted on one machine.  For example,
+		if the virtuser table contained:
+
+			info@foo.com	foo-info
+			info@bar.com	bar-info
+			joe@bar.com	error:nouser No such user here
+			jax@bar.com	error:D.S.N:unavailable Address invalid
+			@baz.org	jane@example.net
+
+		then mail addressed to info@foo.com will be sent to the
+		address foo-info, mail addressed to info@bar.com will be
+		delivered to bar-info, and mail addressed to anyone at baz.org
+		will be sent to jane@example.net, mail to joe@bar.com will
+		be rejected with the specified error message, and mail to
+		jax@bar.com will also have a RFC 1893 compliant error code
+		D.S.N.
+
+		The username from the original address is passed
+		as %1 allowing:
+
+			@foo.org	%1@example.com
+
+		meaning someone@foo.org will be sent to someone@example.com.
+		Additionally, if the local part consists of "user+detail"
+		then "detail" is passed as %2 when a match against user+*
+		is attempted, so entries like
+
+			old+*@foo.org	new+%2@example.com
+			gen+*@foo.org	%2@example.com
+
+		and other forms are possible.
+
+		All the host names on the left hand side (foo.com, bar.com,
+		and baz.org) must be in $=w or $={VirtHost}, the latter can
+		be defined by the macros VIRTUSER_DOMAIN or
+		VIRTUSER_DOMAIN_FILE (analogously to MASQUERADE_DOMAIN and
+		MASQUERADE_DOMAIN_FILE, see below).  If VIRTUSER_DOMAIN or
+		VIRTUSER_DOMAIN_FILE is used, then the entries of $={VirtHost}
+		are added to class 'R', i.e., relaying is allowed to
+		(and from) those domains.  The default map definition is:
+
+			hash /etc/mail/virtusertable
+
+		A new definition can be specified as the second argument of
+		the FEATURE macro, such as
+
+			FEATURE(`virtusertable', `dbm /etc/mail/virtusers')
+
+virtuser_entire_domain
+		If the virtusertable is enabled and VIRTUSER_DOMAIN or
+		VIRTUSER_DOMAIN_FILE is used, this feature will cause
+		addresses to be searched in the map if their domain
+		parts are subdomains of elements in class $={VirtHost}.
+
+ldap_routing	Implement LDAP-based e-mail recipient routing according to
+		the Internet Draft draft-lachman-laser-ldap-mail-routing-01.
+		This provides a method to re-route addresses with a
+		domain portion in the $={LDAPRoute} class to either a
+		different mail host or a different address.  Hosts can
+		be added to this class using LDAPROUTE_DOMAIN and
+		LDAPROUTE_DOMAIN_FILE (analogously to MASQUERADE_DOMAIN and
+		MASQUERADE_DOMAIN_FILE, see below).
+
+		See the LDAP ROUTING section below for more information.
+
+nodns		If you aren't running DNS at your site (for example,
+		you are UUCP-only connected).  It's hard to consider
+		this a "feature", but hey, it had to go somewhere.
+		Actually, as of 8.7 this is a no-op -- remove "dns" from
+		the hosts service switch entry instead.
+
+nullclient	This is a special case -- it creates a configuration file
+		containing nothing but support for forwarding all mail to a
+		central hub via a local SMTP-based network.  The argument
+		is the name of that hub.
+
+		The only other feature that should be used in conjunction
+		with this one is "nocanonify" (this causes addresses to
+		be sent unqualified via the SMTP connection; normally
+		they are qualified with the masquerade name, which
+		defaults to the name of the hub machine).  No mailers
+		should be defined.  No aliasing or forwarding is done.
+
+local_lmtp	Use an LMTP capable local mailer.  The argument to this
+		feature is the pathname of an LMTP capable mailer.  By
+		default, mail.local is used.  This is expected to be the
+		mail.local which came with the 8.9 distribution which is
+		LMTP capable.  The path to mail.local is set by the
+		confEBINDIR m4 variable -- making the default
+		LOCAL_MAILER_PATH /usr/libexec/mail.local.
+		WARNING: This feature sets LOCAL_MAILER_FLAGS unconditionally,
+		i.e., without respecting any definitions in an OSTYPE setting.
+
+local_procmail	Use procmail or another delivery agent as the local mailer.
+		The argument to this feature is the pathname of the
+		delivery agent, which defaults to PROCMAIL_MAILER_PATH.
+		Note that this does NOT use PROCMAIL_MAILER_FLAGS or
+		PROCMAIL_MAILER_ARGS for the local mailer; tweak
+		LOCAL_MAILER_FLAGS and LOCAL_MAILER_ARGS instead, or
+		specify the appropriate parameters.  When procmail is used,
+		the local mailer can make use of the
+		"user+indicator@local.host" syntax; normally the +indicator
+		is just tossed, but by default it is passed as the -a
+		argument to procmail.
+
+		This feature can take up to three arguments:
+
+		1. Path to the mailer program
+		   [default: /usr/local/bin/procmail]
+		2. Argument vector including name of the program
+		   [default: procmail -Y -a $h -d $u]
+		3. Flags for the mailer [default: SPfhn9]
+
+		Empty arguments cause the defaults to be taken.
+
+		For example, this allows it to use the maildrop
+		(http://www.flounder.net/~mrsam/maildrop/) mailer instead
+		by specifying:
+
+		FEATURE(`local_procmail', `/usr/local/bin/maildrop',
+		 `maildrop -d $u')
+
+		or scanmails using:
+
+		FEATURE(`local_procmail', `/usr/local/bin/scanmails')
+
+		WARNING: This feature sets LOCAL_MAILER_FLAGS unconditionally,
+		i.e.,  without respecting any definitions in an OSTYPE setting.
+
+bestmx_is_local	Accept mail as though locally addressed for any host that
+		lists us as the best possible MX record.  This generates
+		additional DNS traffic, but should be OK for low to
+		medium traffic hosts.  The argument may be a set of
+		domains, which will limit the feature to only apply to
+		these domains -- this will reduce unnecessary DNS
+		traffic.  THIS FEATURE IS FUNDAMENTALLY INCOMPATIBLE WITH
+		WILDCARD MX RECORDS!!!  If you have a wildcard MX record
+		that matches your domain, you cannot use this feature.
+
+smrsh		Use the SendMail Restricted SHell (smrsh) provided
+		with the distribution instead of /bin/sh for mailing
+		to programs.  This improves the ability of the local
+		system administrator to control what gets run via
+		e-mail.  If an argument is provided it is used as the
+		pathname to smrsh; otherwise, the path defined by
+		confEBINDIR is used for the smrsh binary -- by default,
+		/usr/libexec/smrsh is assumed.
+
+promiscuous_relay
+		By default, the sendmail configuration files do not permit
+		mail relaying (that is, accepting mail from outside your
+		domain and sending it to another host outside your domain).
+		This option sets your site to allow mail relaying from any
+		site to any site.  In general, it is better to control the
+		relaying more carefully with the access db and the 'R'
+		class ($=R).  Domains can be added to class 'R' by the
+		macros RELAY_DOMAIN or RELAY_DOMAIN_FILE (analogously to
+		MASQUERADE_DOMAIN and MASQUERADE_DOMAIN_FILE, see below).
+
+relay_entire_domain
+		By default, only hosts listed as RELAY in the access db
+		will be allowed to relay.  This option also allows any
+		host in your domain as defined by the 'm' class ($=m).
+
+relay_hosts_only
+		By default, names that are listed as RELAY in the access
+		db and class 'R' ($=R) are domain names, not host names.
+		For example, if you specify ``foo.com'', then mail to or
+		from foo.com, abc.foo.com, or a.very.deep.domain.foo.com
+		will all be accepted for relaying.  This feature changes
+		the behaviour to lookup individual host names only.
+
+relay_based_on_MX
+		Turns on the ability to allow relaying based on the MX
+		records of the host portion of an incoming recipient; that
+		is, if an MX record for host foo.com points to your site,
+		you will accept and relay mail addressed to foo.com.  See
+		description below for more information before using this
+		feature.  Also, see the KNOWNBUGS entry regarding bestmx
+		map lookups.
+
+		FEATURE(`relay_based_on_MX') does not necessarily allow
+		routing of these messages which you expect to be allowed,
+		if route address syntax (or %-hack syntax) is used.  If
+		this is a problem, add entries to the access-table or use
+		FEATURE(`loose_relay_check').
+
+relay_mail_from
+		Allows relaying if the mail sender is listed as RELAY in the
+		access map.  If an optional argument `domain' is given, the
+		domain portion of the mail sender is checked too.  This
+		should only be used if absolutely necessary as the sender
+		address can be easily forged.
+
+relay_local_from
+		Allows relaying if the domain portion of the mail sender
+		is a local host.  This should only be used if absolutely
+		necessary as it opens a window for spammers.  Specifically,
+		they can send mail to your mail server that claims to be
+		from your domain (either directly or via a routed address),
+		and you will go ahead and relay it out to arbitrary hosts
+		on the Internet.
+
+accept_unqualified_senders
+		Normally, MAIL FROM: commands in the SMTP session will be
+		refused if the connection is a network connection and the
+		sender address does not include a domain name.  If your
+		setup sends local mail unqualified (i.e., MAIL FROM: <joe>),
+		you will need to use this feature to accept unqualified
+		sender addresses.  Setting the DaemonPortOptions modifier
+		'u' overrides the default behavior, i.e., unqualified
+		addresses are accepted even without this FEATURE.
+		If this FEATURE is not used, the DaemonPortOptions modifier
+		'f' can be used to enforce fully qualified addresses.
+
+accept_unresolvable_domains
+		Normally, MAIL FROM: commands in the SMTP session will be
+		refused if the host part of the argument to MAIL FROM:
+		cannot be located in the host name service (e.g., an A or
+		MX record in DNS).  If you are inside a firewall that has
+		only a limited view of the Internet host name space, this
+		could cause problems.  In this case you probably want to
+		use this feature to accept all domains on input, even if
+		they are unresolvable.
+
+access_db	Turns on the access database feature.  The access db gives
+		you the ability to allow or refuse to accept mail from
+		specified domains for administrative reasons.  By default,
+		the access database specification is:
+
+			hash /etc/mail/access
+
+		The format of the database is described in the anti-spam
+		configuration control section later in this document.
+
+blacklist_recipients
+		Turns on the ability to block incoming mail for certain
+		recipient usernames, hostnames, or addresses.  For
+		example, you can block incoming mail to user nobody,
+		host foo.mydomain.com, or guest@bar.mydomain.com.
+		These specifications are put in the access db as
+		described in the anti-spam configuration control section
+		later in this document.
+
+rbl		This feature is deprecated! Please use dnsbl instead.
+		Turns on rejection of hosts found in the Realtime Blackhole
+		List.  If an argument is provided it is used as the domain
+		in which blocked hosts are listed; otherwise, the main
+		RBL domain rbl.maps.vix.com is used.  For details, see
+		http://maps.vix.com/rbl/.
+
+dnsbl		Turns on rejection of hosts found in an DNS based rejection
+		list.  If an argument is provided it is used as the name
+		sever to contact; otherwise it defaults to rbl.maps.vix.com.
+		An explanation for an DNS based rejection list can be found
+		http://maps.vix.com/rbl/.  A second argument can be used to
+		change the default error message of
+		Mail from $&{client_addr} refused by blackhole site SERVER
+		where SERVER is replaced by the first argument.  This feature
+		can be included several times to query different DNS based
+		rejection lists.
+
+loose_relay_check
+		Normally, if % addressing is used for a recipient, e.g.
+		user%site@othersite, and othersite is in class 'R', the
+		check_rcpt ruleset will strip @othersite and recheck
+		user@site for relaying.  This feature changes that
+		behavior.  It should not be needed for most installations.
+
+no_default_msa	Don't generate the default MSA daemon, i.e.,
+		DAEMON_OPTIONS(`Port=587,Name=MSA,M=E')
+		To define a MSA daemon with other parameters, use this
+		FEATURE and introduce new settings via DAEMON_OPTIONS().
+
++-------+
+| HACKS |
++-------+
+
+Some things just can't be called features.  To make this clear,
+they go in the hack subdirectory and are referenced using the HACK
+macro.  These will tend to be site-dependent.  The release
+includes the Berkeley-dependent "cssubdomain" hack (that makes
+sendmail accept local names in either Berkeley.EDU or CS.Berkeley.EDU;
+this is intended as a short-term aid while moving hosts into
+subdomains.
+
+
++--------------------+
+| SITE CONFIGURATION |
++--------------------+
+
+    *****************************************************
+    * This section is really obsolete, and is preserved	*
+    * only for back compatibility.  You should plan on	*
+    * using mailertables for new installations.	  In	*
+    * particular, it doesn't work for the newer forms	*
+    * of UUCP mailers, such as uucp-uudom.		*
+    *****************************************************
+
+Complex sites will need more local configuration information, such as
+lists of UUCP hosts they speak with directly.  This can get a bit more
+tricky.  For an example of a "complex" site, see cf/ucbvax.mc.
+
+If your host is known by several different names, you need to augment
+the $=w class.  This is a list of names by which you are known, and
+anything sent to an address using a host name in this list will be
+treated as local mail.  You can do this in two ways:  either create the
+file /etc/mail/local-host-names containing a list of your aliases (one per
+line), and use ``FEATURE(`use_cw_file')'' in the .mc file, or add
+``LOCAL_DOMAIN(`alias.host.name')''.  Be sure you use the fully-qualified
+name of the host, rather than a short name.
+
+The SITECONFIG macro allows you to indirectly reference site-dependent
+configuration information stored in the siteconfig subdirectory.  For
+example, the line
+
+	SITECONFIG(`uucp.ucbvax', `ucbvax', `U')
+
+reads the file uucp.ucbvax for local connection information.  The
+second parameter is the local name (in this case just "ucbvax" since
+it is locally connected, and hence a UUCP hostname).  The third
+parameter is the name of both a macro to store the local name (in
+this case, $U) and the name of the class (e.g., $=U) in which to store
+the host information read from the file.  Another SITECONFIG line reads
+
+	SITECONFIG(`uucp.ucbarpa', `ucbarpa.Berkeley.EDU', `W')
+
+This says that the file uucp.ucbarpa contains the list of UUCP sites
+connected to ucbarpa.Berkeley.EDU.  The $=W class will be used to
+store this list, and $W is defined to be ucbarpa.Berkeley.EDU, that
+is, the name of the relay to which the hosts listed in uucp.ucbarpa
+are connected.  [The machine ucbarpa is gone now, but this
+out-of-date configuration file has been left around to demonstrate
+how you might do this.]
+
+Note that the case of SITECONFIG with a third parameter of ``U'' is
+special; the second parameter is assumed to be the UUCP name of the
+local site, rather than the name of a remote site, and the UUCP name
+is entered into $=w (the list of local hostnames) as $U.UUCP.
+
+The siteconfig file (e.g., siteconfig/uucp.ucbvax.m4) contains nothing
+more than a sequence of SITE macros describing connectivity.  For
+example:
+
+	SITE(`cnmat')
+	SITE(`sgi olympus')
+
+The second example demonstrates that you can use two names on the
+same line; these are usually aliases for the same host (or are at
+least in the same company).
+
+
++--------------------+
+| USING UUCP MAILERS |
++--------------------+
+
+It's hard to get UUCP mailers right because of the extremely ad hoc
+nature of UUCP addressing.  These config files are really designed
+for domain-based addressing, even for UUCP sites.
+
+There are four UUCP mailers available.  The choice of which one to
+use is partly a matter of local preferences and what is running at
+the other end of your UUCP connection.  Unlike good protocols that
+define what will go over the wire, UUCP uses the policy that you
+should do what is right for the other end; if they change, you have
+to change.  This makes it hard to do the right thing, and discourages
+people from updating their software.  In general, if you can avoid
+UUCP, please do.
+
+The major choice is whether to go for a domainized scheme or a
+non-domainized scheme.  This depends entirely on what the other
+end will recognize.  If at all possible, you should encourage the
+other end to go to a domain-based system -- non-domainized addresses
+don't work entirely properly.
+
+The four mailers are:
+
+    uucp-old (obsolete name: "uucp")
+	This is the oldest, the worst (but the closest to UUCP) way of
+	sending messages accros UUCP connections.  It does bangify
+	everything and prepends $U (your UUCP name) to the sender's
+	address (which can already be a bang path itself).  It can
+	only send to one address at a time, so it spends a lot of
+	time copying duplicates of messages.  Avoid this if at all
+	possible.
+
+    uucp-new (obsolete name: "suucp")
+	The same as above, except that it assumes that in one rmail
+	command you can specify several recipients.  It still has a
+	lot of other problems.
+
+    uucp-dom
+	This UUCP mailer keeps everything as domain addresses.
+	Basically, it uses the SMTP mailer rewriting rules.  This mailer
+	is only included if MAILER(`smtp') is also specified.
+
+	Unfortunately, a lot of UUCP mailer transport agents require
+	bangified addresses in the envelope, although you can use
+	domain-based addresses in the message header.  (The envelope
+	shows up as the From_ line on UNIX mail.)  So....
+
+    uucp-uudom
+	This is a cross between uucp-new (for the envelope addresses)
+	and uucp-dom (for the header addresses).  It bangifies the
+	envelope sender (From_ line in messages) without adding the
+	local hostname, unless there is no host name on the address
+	at all (e.g., "wolf") or the host component is a UUCP host name
+	instead of a domain name ("somehost!wolf" instead of
+	"some.dom.ain!wolf").  This is also included only if MAILER(`smtp')
+	is also specified.
+
+Examples:
+
+On host grasp.insa-lyon.fr (UUCP host name "grasp"), the following
+summarizes the sender rewriting for various mailers.
+
+Mailer          sender		rewriting in the envelope
+------		------		-------------------------
+uucp-{old,new}	wolf		grasp!wolf
+uucp-dom	wolf		wolf@grasp.insa-lyon.fr
+uucp-uudom	wolf		grasp.insa-lyon.fr!wolf
+
+uucp-{old,new}	wolf@fr.net	grasp!fr.net!wolf
+uucp-dom	wolf@fr.net	wolf@fr.net
+uucp-uudom	wolf@fr.net	fr.net!wolf
+
+uucp-{old,new}	somehost!wolf	grasp!somehost!wolf
+uucp-dom	somehost!wolf	somehost!wolf@grasp.insa-lyon.fr
+uucp-uudom	somehost!wolf	grasp.insa-lyon.fr!somehost!wolf
+
+If you are using one of the domainized UUCP mailers, you really want
+to convert all UUCP addresses to domain format -- otherwise, it will
+do it for you (and probably not the way you expected).  For example,
+if you have the address foo!bar!baz (and you are not sending to foo),
+the heuristics will add the @uucp.relay.name or @local.host.name to
+this address.  However, if you map foo to foo.host.name first, it
+will not add the local hostname.  You can do this using the uucpdomain
+feature.
+
+
++-------------------+
+| TWEAKING RULESETS |
++-------------------+
+
+For more complex configurations, you can define special rules.
+The macro LOCAL_RULE_3 introduces rules that are used in canonicalizing
+the names.  Any modifications made here are reflected in the header.
+
+A common use is to convert old UUCP addresses to SMTP addresses using
+the UUCPSMTP macro.  For example:
+
+	LOCAL_RULE_3
+	UUCPSMTP(`decvax',	`decvax.dec.com')
+	UUCPSMTP(`research',	`research.att.com')
+
+will cause addresses of the form "decvax!user" and "research!user"
+to be converted to "user@decvax.dec.com" and "user@research.att.com"
+respectively.
+
+This could also be used to look up hosts in a database map:
+
+	LOCAL_RULE_3
+	R$* < @ $+ > $*		$: $1 < @ $(hostmap $2 $) > $3
+
+This map would be defined in the LOCAL_CONFIG portion, as shown below.
+
+Similarly, LOCAL_RULE_0 can be used to introduce new parsing rules.
+For example, new rules are needed to parse hostnames that you accept
+via MX records.  For example, you might have:
+
+	LOCAL_RULE_0
+	R$+ <@ host.dom.ain.>	$#uucp $@ cnmat $: $1 < @ host.dom.ain.>
+
+You would use this if you had installed an MX record for cnmat.Berkeley.EDU
+pointing at this host; this rule catches the message and forwards it on
+using UUCP.
+
+You can also tweak rulesets 1 and 2 using LOCAL_RULE_1 and LOCAL_RULE_2.
+These rulesets are normally empty.
+
+A similar macro is LOCAL_CONFIG.  This introduces lines added after the
+boilerplate option setting but before rulesets.  Do not declare rulesets in
+the LOCAL_CONFIG section.  It can be used to declare local database maps or
+whatever.  For example:
+
+	LOCAL_CONFIG
+	Khostmap hash /etc/mail/hostmap
+	Kyplocal nis -m hosts.byname
+
+
++---------------------------+
+| MASQUERADING AND RELAYING |
++---------------------------+
+
+You can have your host masquerade as another using
+
+	MASQUERADE_AS(`host.domain')
+
+This causes mail being sent to be labeled as coming from the
+indicated host.domain, rather than $j.  One normally masquerades as
+one of one's own subdomains (for example, it's unlikely that
+Berkeley would choose to masquerade as an MIT site).  This
+behaviour is modified by a plethora of FEATUREs; in particular, see
+masquerade_envelope, allmasquerade, limited_masquerade, and
+masquerade_entire_domain.
+
+The masquerade name is not normally canonified, so it is important
+that it be your One True Name, that is, fully qualified and not a
+CNAME.  However, if you use a CNAME, the receiving side may canonify
+it for you, so don't think you can cheat CNAME mapping this way.
+
+Normally the only addresses that are masqueraded are those that come
+from this host (that is, are either unqualified or in $=w, the list
+of local domain names).  You can augment this list using
+
+	MASQUERADE_DOMAIN(`otherhost.domain')
+
+The effect of this is that although mail to user@otherhost.domain
+will not be delivered locally, any mail including any user@otherhost.domain
+will, when relayed, be rewritten to have the MASQUERADE_AS address.
+This can be a space-separated list of names.
+
+If these names are in a file, you can use
+
+	MASQUERADE_DOMAIN_FILE(`filename')
+
+to read the list of names from the indicated file.
+
+To exempt hosts or subdomains from being masqueraded, you can use
+
+	MASQUERADE_EXCEPTION(`host.domain')
+
+This can come handy if you want to masquerade a whole domain
+except for one (or a few) host(s).
+
+Normally only header addresses are masqueraded.  If you want to
+masquerade the envelope as well, use
+
+	FEATURE(`masquerade_envelope')
+
+There are always users that need to be "exposed" -- that is, their
+internal site name should be displayed instead of the masquerade name.
+Root is an example (which has been "exposed" by default prior to 8.10).
+You can add users to this list using
+
+	EXPOSED_USER(`usernames')
+
+This adds users to class E; you could also use something like
+
+	FE/etc/mail/exposed-users
+
+You can also arrange to relay all unqualified names (that is, names
+without @host) to a relay host.  For example, if you have a central
+email server, you might relay to that host so that users don't have
+to have .forward files or aliases.  You can do this using
+
+	define(`LOCAL_RELAY', `mailer:hostname')
+
+The ``mailer:'' can be omitted, in which case the mailer defaults to
+"relay".  There are some user names that you don't want relayed, perhaps
+because of local aliases.  A common example is root, which may be
+locally aliased.  You can add entries to this list using
+
+	LOCAL_USER(`usernames')
+
+This adds users to class L; you could also use something like
+
+	FL/etc/mail/local-users
+
+If you want all incoming mail sent to a centralized hub, as for a
+shared /var/spool/mail scheme, use
+
+	define(`MAIL_HUB', `mailer:hostname')
+
+Again, ``mailer:'' defaults to "relay".  If you define both LOCAL_RELAY
+and MAIL_HUB _AND_ you have FEATURE(`stickyhost'), unqualified names will
+be sent to the LOCAL_RELAY and other local names will be sent to MAIL_HUB.
+Names in $=L will be delivered locally, so you MUST have aliases or
+.forward files for them.
+
+For example, if you are on machine mastodon.CS.Berkeley.EDU and you have
+FEATURE(`stickyhost'), the following combinations of settings will have the
+indicated effects:
+
+email sent to....	eric			  eric@mastodon.CS.Berkeley.EDU
+
+LOCAL_RELAY set to	mail.CS.Berkeley.EDU	  (delivered locally)
+mail.CS.Berkeley.EDU	  (no local aliasing)	    (aliasing done)
+
+MAIL_HUB set to		mammoth.CS.Berkeley.EDU	  mammoth.CS.Berkeley.EDU
+mammoth.CS.Berkeley.EDU	  (aliasing done)	    (aliasing done)
+
+Both LOCAL_RELAY and	mail.CS.Berkeley.EDU	  mammoth.CS.Berkeley.EDU
+MAIL_HUB set as above	  (no local aliasing)	    (aliasing done)
+
+If you do not have FEATURE(`stickyhost') set, then LOCAL_RELAY and
+MAIL_HUB act identically, with MAIL_HUB taking precedence.
+
+If you want all outgoing mail to go to a central relay site, define
+SMART_HOST as well.  Briefly:
+
+	LOCAL_RELAY applies to unqualified names (e.g., "eric").
+	MAIL_HUB applies to names qualified with the name of the
+		local host (e.g., "eric@mastodon.CS.Berkeley.EDU").
+	SMART_HOST applies to names qualified with other hosts or
+		bracketed addresses (e.g., "eric@mastodon.CS.Berkeley.EDU"
+		or "eric@[127.0.0.1]").
+
+However, beware that other relays (e.g., UUCP_RELAY, BITNET_RELAY,
+DECNET_RELAY, and FAX_RELAY) take precedence over SMART_HOST, so if you
+really want absolutely everything to go to a single central site you will
+need to unset all the other relays -- or better yet, find or build a
+minimal config file that does this.
+
+For duplicate suppression to work properly, the host name is best
+specified with a terminal dot:
+
+	define(`MAIL_HUB', `host.domain.')
+	      note the trailing dot ---^
+
+
++--------------+
+| LDAP ROUTING |
++--------------+
+
+FEATURE(`ldap_routing') can be used to implement the IETF Internet Draft
+LDAP Schema for Intranet Mail Routing
+(draft-lachman-laser-ldap-mail-routing-01).  This feature enables
+LDAP-based rerouting of a particular address to either a different host
+or a different address.  The LDAP lookup is first attempted on the full
+address (e.g., user@example.com) and then on the domain portion
+(e.g., @example.com).  Be sure to setup your domain for LDAP routing using
+LDAPROUTE_DOMAIN(), e.g.:
+
+	LDAPROUTE_DOMAIN(`example.com')
+
+By default, the feature will use the schemas as specified in the draft
+and will not reject addresses not found by the LDAP lookup.  However,
+this behavior can be changed by giving additional arguments to the FEATURE()
+command:
+
+	FEATURE(`ldap_routing', <mailHost>, <mailRoutingAddress>, <bounce>)
+
+where <mailHost> is a map definition describing how to lookup an alternative
+mail host for a particular address; <mailRoutingAddress> is a map definition
+describing how to lookup an alternative address for a particular address; and
+the <bounce> argument, if present and not the word "passthru", dictates
+that mail should be bounced if neither a mailHost nor mailRoutingAddress
+is found.
+
+The default <mailHost> map definition is:
+
+	ldap -1 -v mailHost -k (&(objectClass=inetLocalMailRecipient)
+				 (mailLocalAddress=%0))
+
+The default <mailRoutingAddress> map definition is:
+
+	ldap -1 -v mailRoutingAddress -k (&(objectClass=inetLocalMailRecipient)
+					   (mailLocalAddress=%0))
+
+Note that neither includes the LDAP server hostname (-h server) or base DN
+(-b o=org,c=COUNTRY), both necessary for LDAP queries.  It is presumed that
+your .mc file contains a setting for the confLDAP_DEFAULT_SPEC option with
+these settings.  If this is not the case, the map definitions should be
+changed as described above.
+
+The following possibilities exist as a result of an LDAP lookup on an
+address:
+
+	mailHost is	mailRoutingAddress is	Results in
+	-----------	---------------------	----------
+	set to a	set			mail delivered to
+	"local" host				mailRoutingAddress
+
+	set to a	not set			delivered to
+	"local" host				original address
+
+	set to a	set			mailRoutingAddress
+	remote host				relayed to mailHost
+
+	set to a	not set			original address
+	remote host				relayed to mailHost
+
+	not set		set			mail delivered to
+						mailRoutingAddress
+
+	not set		not set			delivered to
+						original address *OR*
+						bounced as unknown user
+
+The term "local" host above means the host specified is in class 'w' ($=w).
+Note that the last case depends on whether the third argument is given
+to the FEATURE() command.  The default is to deliver the message to the
+original address.
+
+The LDAP entries should be set up with an objectClass of
+inetLocalMailRecipient and the address be listed in a mailLocalAddress
+attribute.  If present, there must be only one mailHost attribute and it
+must contain a fully qualified host name as its value.  Similarly, if
+present, there must be only one mailRoutingAddress attribute and it must
+contain an RFC 822 compliant address.  Some example LDAP records (in ldif
+format):
+
+	dn: uid=tom, o=example.com, c=US
+	objectClass: inetLocalMailRecipient
+	mailLocalAddress: tom@example.com
+	mailRoutingAddress: thomas@mailhost.example.com
+
+This would deliver mail for tom@example.com to thomas@mailhost.example.com.
+
+	dn: uid=dick, o=example.com, c=US
+	objectClass: inetLocalMailRecipient
+	mailLocalAddress: dick@example.com
+	mailHost: eng.example.com
+
+This would relay mail for dick@example.com to the same address but redirect
+the mail to MX records listed for the host eng.example.com.
+
+	dn: uid=harry, o=example.com, c=US
+	objectClass: inetLocalMailRecipient
+	mailLocalAddress: harry@example.com
+	mailHost: mktmail.example.com
+	mailRoutingAddress: harry@mkt.example.com
+
+This would relay mail for harry@example.com to the MX records listed for
+the host mktmail.example.com using the new address harry@mkt.example.com
+when talking to that host.
+
+	dn: uid=virtual.example.com, o=example.com, c=US
+	objectClass: inetLocalMailRecipient
+	mailLocalAddress: @virtual.example.com
+	mailHost: server.example.com
+	mailRoutingAddress: virtual@example.com
+
+This would send all mail destined for any username @virtual.example.com to
+the machine server.example.com's MX servers and deliver to the address
+virtual@example.com on that relay machine.
+
+
++---------------------------------+
+| ANTI-SPAM CONFIGURATION CONTROL |
++---------------------------------+
+
+The primary anti-spam features available in sendmail are:
+
+* Relaying is denied by default.
+* Better checking on sender information.
+* Access database.
+* Header checks.
+
+Relaying (transmission of messages from a site outside your domain to
+another site outside your domain) is denied by default.  Note that
+this changed in sendmail 8.9; previous versions allowed relaying by
+default.  If you want to revert to the old behaviour, you will need
+to use FEATURE(`promiscuous_relay').  You can allow certain domains to
+relay through your server by adding their domain name or IP address to
+class 'R' ($=R) using RELAY_DOMAIN() and RELAY_DOMAIN_FILE() or via the
+access database (described below).
+
+If you use
+
+	FEATURE(`relay_entire_domain')
+
+then any host in any of your local domains (that is, the $=m class)
+will be relayed (that is, you will accept mail either to or from any
+host in your domain).
+
+You can also allow relaying based on the MX records of the host
+portion of an incoming recipient address by using
+
+	FEATURE(`relay_based_on_MX')
+
+For example, if your server receives a recipient of user@domain.com
+and domain.com lists your server in its MX records, the mail will be
+accepted for relay to domain.com.  Note that this will stop spammers
+from using your host to relay spam but it will not stop outsiders from
+using your server as a relay for their site (that is, they set up an
+MX record pointing to your mail server, and you will relay mail addressed
+to them without any prior arrangement).  Along the same lines,
+
+	FEATURE(`relay_local_from')
+
+will allow relaying if the sender specifies a return path (i.e.
+MAIL FROM: <user@domain>) domain which is a local domain.  This a
+dangerous feature as it will allow spammers to spam using your mail
+server by simply specifying a return address of user@your.domain.com.
+It should not be used unless absolutely necessary.
+A slightly better solution is
+
+	FEATURE(`relay_mail_from')
+
+which allows relaying if the mail sender is listed as RELAY in the
+access map.  If an optional argument `domain' is given, the domain
+portion of the mail sender is also checked to allowing relaying.
+This option only works together with the tag From: for the LHS of
+the access map entries (see below: Finer control...).
+
+
+If source routing is used in the recipient address (i.e.
+RCPT TO: <user%site.com@othersite.com>), sendmail will check
+user@site.com for relaying if othersite.com is an allowed relay host
+in either class 'R', class 'm' if FEATURE(`relay_entire_domain') is used,
+or the access database if FEATURE(`access_db') is used.  To prevent
+the address from being stripped down, use:
+
+	FEATURE(`loose_relay_check')
+
+If you think you need to use this feature, you probably do not.  This
+should only be used for sites which have no control over the addresses
+that they provide a gateway for.  Use this FEATURE with caution as it
+can allow spammers to relay through your server if not setup properly.
+
+NOTICE: It is possible to relay mail through a system which the anti-relay
+rules do not prevent: the case of a system that does use FEATURE(`nouucp',
+`nospecial') (system A) and relays local messages to a mail hub (e.g., via
+LOCAL_RELAY or LUSER_RELAY) (system B).  If system B doesn't use
+FEATURE(`nouucp') at all, addresses of the form
+<example.net!user@local.host> would be relayed to <user@example.net>.
+System A doesn't recognize `!' as an address separator and therefore
+forwards it to the mail hub which in turns relays it because it came from
+a trusted local host.  So if a mailserver allows UUCP (bang-format)
+addresses, all systems from which it allows relaying should do the same
+or reject those addresses.
+
+As of 8.9, sendmail will refuse mail if the MAIL FROM: parameter has
+an unresolvable domain (i.e., one that DNS, your local name service,
+or special case rules in ruleset 3 cannot locate).  If you want to
+continue to accept such domains, e.g., because you are inside a
+firewall that has only a limited view of the Internet host name space
+(note that you will not be able to return mail to them unless you have
+some "smart host" forwarder), use
+
+	FEATURE(`accept_unresolvable_domains')
+
+sendmail will also refuse mail if the MAIL FROM: parameter is not
+fully qualified (i.e., contains a domain as well as a user).  If you
+want to continue to accept such senders, use
+
+	FEATURE(`accept_unqualified_senders')
+
+Setting the DaemonPortOptions modifier 'u' overrides the default behavior,
+i.e., unqualified addresses are accepted even without this FEATURE.  If
+this FEATURE is not used, the DaemonPortOptions modifier 'f' can be used
+to enforce fully qualified addresses.
+
+An ``access'' database can be created to accept or reject mail from
+selected domains.  For example, you may choose to reject all mail
+originating from known spammers.  To enable such a database, use
+
+	FEATURE(`access_db')
+
+The FEATURE macro can accept a second parameter giving the key file
+definition for the database; for example
+
+	FEATURE(`access_db', `hash /etc/mail/access')
+
+Remember, since /etc/mail/access is a database, after creating the text
+file as described below, you must use makemap to create the database
+map.  For example:
+
+	makemap hash /etc/mail/access < /etc/mail/access
+
+The table itself uses e-mail addresses, domain names, and network
+numbers as keys.  For example,
+
+	spammer@aol.com		REJECT
+	cyberspammer.com	REJECT
+	192.168.212		REJECT
+
+would refuse mail from spammer@aol.com, any user from cyberspammer.com
+(or any host within the cyberspammer.com domain), and any host on the
+192.168.212.* network.
+
+The value part of the map can contain:
+
+	OK		Accept mail even if other rules in the
+			running ruleset would reject it, for example,
+			if the domain name is unresolvable.
+	RELAY		Accept mail addressed to the indicated domain or
+			received from the indicated domain for relaying
+			through your SMTP server.  RELAY also serves as
+			an implicit OK for the other checks.
+	REJECT		Reject the sender or recipient with a general
+			purpose message.
+	DISCARD		Discard the message completely using the
+			$#discard mailer.  For sender addresses it
+			indicates that you should discard anything
+			received from the indicated domain.  If it
+			is used for recipients, it affects only
+			the designated recipients, not the whole
+			message.
+	### any text	where ### is an RFC 821 compliant error code
+			and "any text" is a message to return for
+			the command.
+	ERROR:### any text
+			as above, but useful to mark error messages as such.
+	ERROR:D.S.N:### any text
+			where D.S.N is an RFC 1893 compliant error code
+			and the rest as above.
+
+For example:
+
+	cyberspammer.com	550 We don't accept mail from spammers
+	okay.cyberspammer.com	OK
+	sendmail.org		RELAY
+	128.32			RELAY
+	1:2:3:4:5:6:7		RELAY
+	[127.0.0.3]		OK
+	[1:2:3:4:5:6:7:8]	OK
+
+would accept mail from okay.cyberspammer.com, but would reject mail from
+all other hosts at cyberspammer.com with the indicated message.  It would
+allow relaying mail from and to any hosts in the sendmail.org domain, and
+allow relaying from the 128.32.*.* network and the IPv6 1:2:3:4:5:6:7:*
+network.  The latter two entries are for checks against ${client_name} if
+the IP address doesn't resolve to a hostname (or is considered as "may be
+forged").
+
+Warning: if you change the RFC 821 compliant error code from the default
+value of 550, then you should probably also change the RFC 1893 compliant
+error code to match it.  For example, if you use
+
+	user@example.com	450 mailbox full
+
+the error returned would be "450 4.0.0 mailbox full" which is wrong.
+Use "450 4.2.2 mailbox full" or "ERROR:4.2.2:450 mailbox full"
+instead.
+
+Note, UUCP users may need to add hostname.UUCP to the access database
+or class 'R' ($=R).  If you also use:
+
+	FEATURE(`relay_hosts_only')
+
+then the above example will allow relaying for sendmail.org, but not
+hosts within the sendmail.org domain.  Note that this will also require
+hosts listed in class 'R' ($=R) to be fully qualified host names.
+
+You can also use the access database to block sender addresses based on
+the username portion of the address.  For example:
+
+	FREE.STEALTH.MAILER@	550 Spam not accepted
+
+Note that you must include the @ after the username to signify that
+this database entry is for checking only the username portion of the
+sender address.
+
+If you use:
+
+	FEATURE(`blacklist_recipients')
+
+then you can add entries to the map for local users, hosts in your
+domains, or addresses in your domain which should not receive mail:
+
+	badlocaluser@		550 Mailbox disabled for this username
+	host.mydomain.com	550 That host does not accept mail
+	user@otherhost.mydomain.com	550 Mailbox disabled for this recipient
+
+This would prevent a recipient of badlocaluser@mydomain.com, any
+user at host.mydomain.com, and the single address
+user@otherhost.mydomain.com from receiving mail.  Please note: a
+local username must be now tagged with an @ (this is consistent
+with the check of the sender address, and hence it is possible to
+distinguish between hostnames and usernames).  Enabling this feature
+will keep you from sending mails to all addresses that have an
+error message or REJECT as value part in the access map.  Taking
+the example from above:
+
+	spammer@aol.com		REJECT
+	cyberspammer.com	REJECT
+
+Mail can't be sent to spammer@aol.com or anyone at cyberspammer.com.
+
+There is also a ``Realtime Blackhole List'' run by the MAPS project
+at http://maps.vix.com/.  This is a database maintained in DNS of
+spammers.  To use this database, use
+
+	FEATURE(`dnsbl')
+
+This will cause sendmail to reject mail from any site in the
+Realtime Blackhole List database.  You can specify an alternative
+RBL domain to check by specifying an argument to the FEATURE.
+A second argument can be used to change the default error message
+Mail from $&{client_addr} refused by blackhole site DOMAIN
+where DOMAIN is replaced by the first argument.  This FEATURE can
+be included several times to query different DNS based rejection
+lists, e.g., the dial-up user list (see http://maps.vix.com/dul/).
+
+The features described above make use of the check_relay, check_mail,
+and check_rcpt rulesets.  If you wish to include your own checks,
+you can put your checks in the rulesets Local_check_relay,
+Local_check_mail, and Local_check_rcpt.  For example if you wanted to
+block senders with all numeric usernames (i.e. 2312343@bigisp.com),
+you would use Local_check_mail and the new regex map:
+
+	LOCAL_CONFIG
+	Kallnumbers regex -a@MATCH ^[0-9]+$
+
+	LOCAL_RULESETS
+	SLocal_check_mail
+	# check address against various regex checks
+	R$*				$: $>Parse0 $>3 $1
+	R$+ < @ bigisp.com. > $*	$: $(allnumbers $1 $)
+	R@MATCH				$#error $: 553 Header Error
+
+These rules are called with the original arguments of the corresponding
+check_* ruleset.  If the local ruleset returns $#OK, no further checking
+is done by the features described above and the mail is accepted.  If the
+local ruleset resolves to a mailer (such as $#error or $#discard), the
+appropriate action is taken.  Otherwise, the results of the local
+rewriting are ignored.
+
+Finer control by using tags for the LHS of the access map
+
+Read this section only if the options listed so far are not sufficient
+for your purposes.  There is now the option to tag entries in the
+access map according to their type.  Three tags are available:
+
+	Connect:	connection information (${client_addr}, ${client_name})
+	From:		sender
+	To:		recipient
+
+If the required item is looked up in a map, it will be tried first
+with the corresponding tag in front, then (as fallback to enable
+backward compatibility) without any tag.  For example,
+
+	From:spammer@some.dom	REJECT
+	To:friend.domain	RELAY
+	Connect:friend.domain	OK
+	Connect:from.domain	RELAY
+	From:good@another.dom	OK
+	From:another.dom	REJECT
+
+This would deny mails from spammer@some.dom but you could still
+send mail to that address even if FEATURE(`blacklist_recipients')
+is enabled.  Your system will allow relaying to friend.domain, but
+not from it (unless enabled by other means).  Connections from that
+domain will be allowed even if it ends up in one of the DNS based
+rejection lists.  Relaying is enabled from from.domain but not to
+it (since relaying is based on the connection information for
+outgoing relaying, the tag Connect: must be used; for incoming
+relaying, which is based on the recipient address, To: must be
+used).  The last two entries allow mails from good@another.dom but
+reject mail from all other addresses with another.dom as domain
+part.
+
+Delay all checks
+
+By using FEATURE(`delay_checks') the rulesets check_mail and check_relay
+will not be called when a client connects or issues a MAIL command,
+respectively.  Instead, those rulesets will be called by the check_rcpt
+ruleset; they will be skipped if a sender has been authenticated using
+a "trusted" mechanism, i.e., one that is defined via TRUST_AUTH_MECH().
+Moreover, an argument can be specified for this option:
+
+	friend: enable spamfriend test
+	hater: enable spamhater test
+
+If such an argument is given, the recipient will be looked up in the access
+map (using the tag To:).  If the argument is `friend', then the other
+rulesets will be skipped if the recipient address is found and has RHS
+spamfriend.  If the argument is `hater', then the other rulesets will be
+applied if the recipient address is found and has RHS spamhater.
+
+This allows for simple exceptions from the tests, e.g., by activating
+the spamfriend option and having
+
+	To:abuse@	SPAMFRIEND
+
+in the access map, mail to abuse@localdomain will get through.  It is
+also possible to specify a full address or an address with +detail:
+
+	To:abuse@abuse.my.domain	SPAMFRIEND
+	To:me+abuse@		SPAMFRIEND
+
+
+Header Checks
+
+You can also reject mail on the basis of the contents of headers.
+This is done by adding a ruleset call to the 'H' header definition command
+in sendmail.cf.  For example, this can be used to check the validity of
+a Message-ID: header:
+
+	LOCAL_RULESETS
+	HMessage-Id: $>CheckMessageId
+
+	SCheckMessageId
+	R< $+ @ $+ >		$@ OK
+	R$*			$#error $: 553 Header Error
+
+The alternative format:
+
+	HSubject: $>+CheckSubject
+
+that is, $>+ instead of $>, gives the full Subject: header including
+comments to the ruleset (comments in parentheses () are stripped
+by default).
+
+A default ruleset for headers which don't have a specific ruleset
+defined for them can be given by:
+
+	H*: $>CheckHdr
+
+After all of the headers are read, the check_eoh ruleset will be called for
+any final header-related checks.  The ruleset is called with the number of
+headers and the size of all of the headers in bytes separated by $|.  One
+example usage is to reject messages which do not have a Message-Id:
+header.  However, the Message-Id: header is *NOT* a required header and is
+not a guaranteed spam indicator.  This ruleset is an example and should
+probably not be used in production.
+
+	LOCAL_CONFIG
+	Kstorage macro
+
+	LOCAL_RULESETS
+	HMessage-Id: $>CheckMessageId
+
+	SCheckMessageId
+	# Record the presence of the header
+	R$*			$: $(storage {MessageIdCheck} $@ OK $) $1
+	R< $+ @ $+ >		$@ OK
+	R$*			$#error $: 553 Header Error
+
+	Scheck_eoh
+	# Check the macro
+	R$*			$: < $&{MessageIdCheck} >
+	# Clear the macro for the next message
+	R$*			$: $(storage {MessageIdCheck} $) $1
+	# Has a Message-Id: header
+	R< $+ >			$@ OK
+	# Allow missing Message-Id: from local mail
+	R$*			$: < $&{client_name} >
+	R< >			$@ OK
+	R< $=w >		$@ OK
+	# Otherwise, reject the mail
+	R$*			$#error $: 553 Header Error
+
++--------------------------------+
+| SMTP AUTHENTICATION            |
++--------------------------------+
+
+The macros ${auth_authen}, ${auth_author}, and ${auth_type} can be
+used in anti-relay rulesets to allow relaying for those users that
+authenticated themselves.  A very simple example is:
+
+SLocal_check_rcpt
+R$*		$: $&{auth_type}
+R$+		$# OK
+
+which checks whether a user has successfully authenticated using
+any available mechanism.  Depending on the setup of the CYRUS SASL 
+library, more sophisticated rulesets might be required, e.g.,
+
+SLocal_check_rcpt
+R$*		$: $&{auth_type} $| $&{auth_authen}
+RDIGEST-MD5 $| $+@$=w	$# OK
+
+to allow relaying for users that authenticated using DIGEST-MD5
+and have an identity in the local domains.
+
+The ruleset Strust_auth is used to determine whether a given AUTH=
+parameter (that is passed to this ruleset) should be trusted.  This
+ruleset may make use of the other ${auth_*} macros.  Only if the
+ruleset resolves to the error mailer, the AUTH= parameter is not
+trusted.  A user supplied ruleset Local_trust_auth can be written
+to modify the default behavior, which only trust the AUTH=
+parameter if it is identical to the authenticated user.
+
+Per default, relaying is allowed for any user who authenticated
+via a "trusted" mechanism, i.e., one that is defined via
+TRUST_AUTH_MECH(`list of mechanisms')
+
++--------------------------------+
+| ADDING NEW MAILERS OR RULESETS |
++--------------------------------+
+
+Sometimes you may need to add entirely new mailers or rulesets.  They
+should be introduced with the constructs MAILER_DEFINITIONS and
+LOCAL_RULESETS respectively.  For example:
+
+	MAILER_DEFINITIONS
+	Mmymailer, ...
+	...
+
+	LOCAL_RULESETS
+	Smyruleset
+	...
+
+
+#if _FFR_MILTER
++---------------------------+
+| ADDING NEW MAILER FILTERS |
++---------------------------+
+
+Sendmail supports mail filters to filter incoming SMTP messages according
+to the "Sendmail Mail Filter API" documentation.  These filters can be
+configured in your mc file using the two commands:
+
+	MAIL_FILTER(`name', `equates')
+	INPUT_MAIL_FILTER(`name', `equates')
+
+The first command, MAIL_FILTER(), simply defines a filter with the given
+name and equates.  For example:
+
+	MAIL_FILTER(`archiver', `S=local:/var/run/archivesock, F=R')
+
+This creates the equivalent sendmail.cf entry:
+
+	Xarchive, S=local:/var/run/archivesock, F=R
+
+The INPUT_MAIL_FILTER() command performs the same actions as MAIL_FILTER
+but also populates the m4 variable `confINPUT_MAIL_FILTERS' with the name
+of the filter such that the filter will actually be called by sendmail.
+
+For example, the two commands:
+
+	INPUT_MAIL_FILTER(`archive', `S=local:/var/run/archivesock, F=R')
+	INPUT_MAIL_FILTER(`spamcheck', `S=inet:2525@localhost, F=T')
+
+are equivalent to the three commands:
+
+	MAIL_FILTER(`archive', `S=local:/var/run/archivesock, F=R')
+	MAIL_FILTER(`spamcheck', `S=inet:2525@localhost, F=T')
+	define(`confINPUT_MAIL_FILTERS', `archive, spamcheck')
+
+In general, INPUT_MAIL_FILTER() should be used unless you need to define
+more filters than you want to use for `confINPUT_MAIL_FILTERS'.
+
+Note that setting `confINPUT_MAIL_FILTERS' after any INPUT_MAIL_FILTER()
+commands will clear the list created by the prior INPUT_MAIL_FILTER()
+commands.
+#endif /* _FFR_MILTER */
+
+
++-------------------------------+
+| NON-SMTP BASED CONFIGURATIONS |
++-------------------------------+
+
+These configuration files are designed primarily for use by
+SMTP-based sites.  They may not be well tuned for UUCP-only or
+UUCP-primarily nodes (the latter is defined as a small local net
+connected to the rest of the world via UUCP).  However, there is
+one hook to handle some special cases.
+
+You can define a ``smart host'' that understands a richer address syntax
+using:
+
+	define(`SMART_HOST', `mailer:hostname')
+
+In this case, the ``mailer:'' defaults to "relay".  Any messages that
+can't be handled using the usual UUCP rules are passed to this host.
+
+If you are on a local SMTP-based net that connects to the outside
+world via UUCP, you can use LOCAL_NET_CONFIG to add appropriate rules.
+For example:
+
+	define(`SMART_HOST', `uucp-new:uunet')
+	LOCAL_NET_CONFIG
+	R$* < @ $* .$m. > $*	$#smtp $@ $2.$m. $: $1 < @ $2.$m. > $3
+
+This will cause all names that end in your domain name ($m) via
+SMTP; anything else will be sent via uucp-new (smart UUCP) to uunet.
+If you have FEATURE(`nocanonify'), you may need to omit the dots after
+the $m.  If you are running a local DNS inside your domain which is
+not otherwise connected to the outside world, you probably want to
+use:
+
+	define(`SMART_HOST', `smtp:fire.wall.com')
+	LOCAL_NET_CONFIG
+	R$* < @ $* . > $*	$#smtp $@ $2. $: $1 < @ $2. > $3
+
+That is, send directly only to things you found in your DNS lookup;
+anything else goes through SMART_HOST.
+
+You may need to turn off the anti-spam rules in order to accept
+UUCP mail with FEATURE(`promiscuous_relay') and
+FEATURE(`accept_unresolvable_domains').
+
+
++-----------+
+| WHO AM I? |
++-----------+
+
+Normally, the $j macro is automatically defined to be your fully
+qualified domain name (FQDN).  Sendmail does this by getting your
+host name using gethostname and then calling gethostbyname on the
+result.  For example, in some environments gethostname returns
+only the root of the host name (such as "foo"); gethostbyname is
+supposed to return the FQDN ("foo.bar.com").  In some (fairly rare)
+cases, gethostbyname may fail to return the FQDN.  In this case
+you MUST define confDOMAIN_NAME to be your fully qualified domain
+name.  This is usually done using:
+
+	Dmbar.com
+	define(`confDOMAIN_NAME', `$w.$m')dnl
+
+
++--------------------+
+| USING MAILERTABLES |
++--------------------+
+
+To use FEATURE(`mailertable'), you will have to create an external
+database containing the routing information for various domains.
+For example, a mailertable file in text format might be:
+
+	.my.domain		xnet:%1.my.domain
+	uuhost1.my.domain	uucp-new:uuhost1
+	.bitnet			smtp:relay.bit.net
+
+This should normally be stored in /etc/mail/mailertable.  The actual
+database version of the mailertable is built using:
+
+	makemap hash /etc/mail/mailertable < /etc/mail/mailertable
+
+The semantics are simple.  Any LHS entry that does not begin with
+a dot matches the full host name indicated.  LHS entries beginning
+with a dot match anything ending with that domain name -- that is,
+they can be thought of as having a leading "*" wildcard.  Matching
+is done in order of most-to-least qualified -- for example, even
+though ".my.domain" is listed first in the above example, an entry
+of "uuhost1.my.domain" will match the second entry since it is
+more explicit.  Note: e-mail to "user@my.domain" does not match
+any entry in the above table. You need to have something like:
+
+	my.domain		esmtp:host.my.domain
+
+The RHS should always be a "mailer:host" pair.  The mailer is the
+configuration name of a mailer (that is, an `M' line in the
+sendmail.cf file).  The "host" will be the hostname passed to
+that mailer.  In domain-based matches (that is, those with leading
+dots) the "%1" may be used to interpolate the wildcarded part of
+the host name.  For example, the first line above sends everything
+addressed to "anything.my.domain" to that same host name, but using
+the (presumably experimental) xnet mailer.
+
+In some cases you may want to temporarily turn off MX records,
+particularly on gateways.  For example, you may want to MX
+everything in a domain to one machine that then forwards it
+directly.  To do this, you might use the DNS configuration:
+
+	*.domain.	IN	MX	0	relay.machine
+
+and on relay.machine use the mailertable:
+
+	.domain		smtp:[gateway.domain]
+
+The [square brackets] turn off MX records for this host only.
+If you didn't do this, the mailertable would use the MX record
+again, which would give you an MX loop.
+
+
++--------------------------------+
+| USING USERDB TO MAP FULL NAMES |
++--------------------------------+
+
+The user database was not originally intended for mapping full names
+to login names (e.g., Eric.Allman => eric), but some people are using
+it that way.  (it is recommended that you set up aliases for this
+purpose instead -- since you can specify multiple alias files, this
+is fairly easy.)  The intent was to locate the default maildrop at
+a site, but allow you to override this by sending to a specific host.
+
+If you decide to set up the user database in this fashion, it is
+imperative that you not use FEATURE(`stickyhost') -- otherwise,
+e-mail sent to Full.Name@local.host.name will be rejected.
+
+To build the internal form of the user database, use:
+
+	makemap btree /etc/mail/userdb < /etc/mail/userdb.txt
+
+As a general rule, it is an extremely bad idea to using full names
+as e-mail addresses, since they are not in any sense unique.  For
+example, the Unix software-development community has at least two
+well-known Peter Deutsches, and at one time Bell Labs had two
+Stephen R. Bournes with offices along the same hallway.  Which one
+will be forced to suffer the indignity of being Stephen_R_Bourne_2?
+The less famous of the two, or the one that was hired later?
+
+Finger should handle full names (and be fuzzy).  Mail should use
+handles, and not be fuzzy.
+
+
++--------------------------------+
+| MISCELLANEOUS SPECIAL FEATURES |
++--------------------------------+
+
+Plussed users
+	Sometimes it is convenient to merge configuration on a
+	centralized mail machine, for example, to forward all
+	root mail to a mail server.  In this case it might be
+	useful to be able to treat the root addresses as a class
+	of addresses with subtle differences.  You can do this
+	using plussed users.  For example, a client might include
+	the alias:
+
+		root:  root+client1@server
+
+	On the server, this will match an alias for "root+client1".
+	If that is not found, the alias "root+*" will be tried,
+	then "root".
+
+
++----------------+
+| SECURITY NOTES |
++----------------+
+
+A lot of sendmail security comes down to you.  Sendmail 8 is much
+more careful about checking for security problems than previous
+versions, but there are some things that you still need to watch
+for.  In particular:
+
+* Make sure the aliases file isn't writable except by trusted
+  system personnel.  This includes both the text and database
+  version.
+
+* Make sure that other files that sendmail reads, such as the
+  mailertable, are only writable by trusted system personnel.
+
+* The queue directory should not be world writable PARTICULARLY
+  if your system allows "file giveaways" (that is, if a non-root
+  user can chown any file they own to any other user).
+
+* If your system allows file giveaways, DO NOT create a publically
+  writable directory for forward files.  This will allow anyone
+  to steal anyone else's e-mail.  Instead, create a script that
+  copies the .forward file from users' home directories once a
+  night (if you want the non-NFS-mounted forward directory).
+
+* If your system allows file giveaways, you'll find that
+  sendmail is much less trusting of :include: files -- in
+  particular, you'll have to have /SENDMAIL/ANY/SHELL/ in
+  /etc/shells before they will be trusted (that is, before
+  files and programs listed in them will be honored).
+
+In general, file giveaways are a mistake -- if you can turn them
+off, do so.
+
+
++--------------------------------+
+| TWEAKING CONFIGURATION OPTIONS |
++--------------------------------+
+
+There are a large number of configuration options that don't normally
+need to be changed.  However, if you feel you need to tweak them, you
+can define the following M4 variables.  This list is shown in four
+columns:  the name you define, the default value for that definition,
+the option or macro that is affected (either Ox for an option or Dx
+for a macro), and a brief description.  Greater detail of the semantics
+can be found in the Installation and Operations Guide.
+
+Some options are likely to be deprecated in future versions -- that is,
+the option is only included to provide back-compatibility.  These are
+marked with "*".
+
+Remember that these options are M4 variables, and hence may need to
+be quoted.  In particular, arguments with commas will usually have to
+be ``double quoted, like this phrase'' to avoid having the comma
+confuse things.  This is common for alias file definitions and for
+the read timeout.
+

+================	=============	=======================
+confMAILER_NAME		$n macro	[MAILER-DAEMON] The sender name used
+					for internally generated outgoing
+					messages.
+confDOMAIN_NAME		$j macro	If defined, sets $j.  This should
+					only be done if your system cannot
+					determine your local domain name,
+					and then it should be set to
+					$w.Foo.COM, where Foo.COM is your
+					domain name.
+confCF_VERSION		$Z macro	If defined, this is appended to the
+					configuration version name.
+confFROM_HEADER		From:		[$?x$x <$g>$|$g$.] The format of an

+			$.$?{auth_type}(authenticated)
+			$.by $j ($v/$Z)$?r with $r$. id $i$?u
+			for $u; $|;

+confCW_FILE		Fw class	[/etc/mail/local-host-names] Name
+					of file used to get the local
+					additions to the $=w (local host
+					names) class.

+					file used to get the local
+					additions to the $=t (trusted
+					users) class.
+confCR_FILE		FR class	[/etc/mail/relay-domains] Name of
+					file used to get the local additions
+					to the $=R (hosts allowed to relay)

+					See also FEATURE(`use_ct_file').
+confTRUSTED_USER	TrustedUser	[no default] Trusted user for file
+					ownership and starting the daemon.
+					Not to be confused with
+					confTRUSTED_USERS (see above).
+confSMTP_MAILER		-		[esmtp] The mailer name used when
+					SMTP connectivity is required.
+					One of "smtp", "smtp8",
+					"esmtp", or "dsmtp".
+confUUCP_MAILER		-		[uucp-old] The mailer to be used by

+confLOCAL_MAILER	-		[local] The mailer name used when
+					local connectivity is required.
+					Almost always "local".
+confRELAY_MAILER	-		[relay] The default mailer name used
+					for relaying any mail (e.g., to a
+					BITNET_RELAY, a SMART_HOST, or
+					whatever).  This can reasonably be
+					"uucp-new" if you are on a
+					UUCP-connected site.
+confSEVEN_BIT_INPUT	SevenBitInput	[False] Force input to seven bits?
+confEIGHT_BIT_HANDLING	EightBitMode	[pass8] 8-bit data handling
+confALIAS_WAIT		AliasWait	[10m] Time to wait for alias file
+					rebuild until you get bored and
+					decide that the apparently pending
+					rebuild failed.
+confMIN_FREE_BLOCKS	MinFreeBlocks	[100] Minimum number of free blocks on
+					queue filesystem to accept SMTP mail.
+					(Prior to 8.7 this was minfree/maxsize,
+					where minfree was the number of free
+					blocks and maxsize was the maximum
+					message size.  Use confMAX_MESSAGE_SIZE
+					for the second value now.)
+confMAX_MESSAGE_SIZE	MaxMessageSize	[infinite] The maximum size of messages
+					that will be accepted (in bytes).
+confBLANK_SUB		BlankSub	[.] Blank (space) substitution

+					recipients.
+confDELIVERY_MODE	DeliveryMode	[background] Default delivery mode.
+confAUTO_REBUILD	AutoRebuildAliases
+					[False] Automatically rebuild alias
+					file if needed.
+					There is a potential for a denial
+					of service attack if this is set.
+					This option is deprecated and will
+					be removed from a future version.
+confERROR_MODE		ErrorMode	[print] Error message mode.
+confERROR_MESSAGE	ErrorHeader	[undefined] Error message header/file.
+confSAVE_FROM_LINES	SaveFromLine	Save extra leading From_ lines.
+confTEMP_FILE_MODE	TempFileMode	[0600] Temporary file mode.
+confMATCH_GECOS		MatchGECOS	[False] Match GECOS field.
+confMAX_HOP		MaxHopCount	[25] Maximum hop count.
+confIGNORE_DOTS*	IgnoreDots	[False; always False in -bs or -bd

+confBIND_OPTS		ResolverOptions	[undefined] Default options for DNS
+					resolver.
+confMIME_FORMAT_ERRORS*	SendMimeErrors	[True] Send error messages as MIME-
+					encapsulated messages per RFC 1344.
+confFORWARD_PATH	ForwardPath	[$z/.forward.$w:$z/.forward]
+					The colon-separated list of places to
+					search for .forward files.  N.B.: see
+					the Security Notes section.
+confMCI_CACHE_SIZE	ConnectionCacheSize
+					[2] Size of open connection cache.
+confMCI_CACHE_TIMEOUT	ConnectionCacheTimeout
+					[5m] Open connection cache timeout.
+confHOST_STATUS_DIRECTORY HostStatusDirectory
+					[undefined] If set, host status is kept
+					on disk between sendmail runs in the
+					named directory tree.  This need not be
+					a full pathname, in which case it is
+					interpreted relative to the queue
+					directory.
+confSINGLE_THREAD_DELIVERY  SingleThreadDelivery
+					[False] If this option and the
+					HostStatusDirectory option are both
+					set, single thread deliveries to other
+					hosts.  That is, don't allow any two
+					sendmails on this host to connect
+					simultaneously to any other single
+					host.  This can slow down delivery in
+					some cases, in particular since a
+					cached but otherwise idle connection
+					to a host will prevent other sendmails
+					from connecting to the other host.
+confUSE_ERRORS_TO*	UseErrorsTo	[False] Use the Errors-To: header to
+					deliver error messages.  This should
+					not be necessary because of general
+					acceptance of the envelope/header
+					distinction.
+confLOG_LEVEL		LogLevel	[9] Log level.
+confME_TOO		MeToo		[True] Include sender in group
+					expansions.  This option is
+					deprecated and will be removed from
+					a future version.
+confCHECK_ALIASES	CheckAliases	[False] Check RHS of aliases when
+					running newaliases.  Since this does
+					DNS lookups on every address, it can
+					slow down the alias rebuild process
+					considerably on large alias files.
+confOLD_STYLE_HEADERS*	OldStyleHeaders	[True] Assume that headers without
+					special chars are old style.
+confCLIENT_OPTIONS	ClientPortOptions

+confTO_INITIAL		Timeout.initial	[5m] The timeout waiting for a response
+					on the initial connect.
+confTO_CONNECT		Timeout.connect	[0] The timeout waiting for an initial
+					connect() to complete.  This can only
+					shorten connection timeouts; the kernel
+					silently enforces an absolute maximum
+					(which varies depending on the system).
+confTO_ICONNECT		Timeout.iconnect
+					[undefined] Like Timeout.connect, but
+					applies only to the very first attempt
+					to connect to a host in a message.

+confTO_QUEUEWARN	Timeout.queuewarn
+					[4h] The timeout before a warning

+					them that the message has been
+					deferred.
+confTO_QUEUEWARN_NORMAL	Timeout.queuewarn.normal

+confTO_QUEUEWARN_URGENT	Timeout.queuewarn.urgent
+					[undefined] As above, for urgent
+					priority messages.
+confTO_QUEUEWARN_NONURGENT
+			Timeout.queuewarn.non-urgent
+					[undefined] As above, for non-urgent
+					(low) priority messages.
+confTO_HOSTSTATUS	Timeout.hoststatus
+					[30m] How long information about host
+					statuses will be maintained before it
+					is considered stale and the host should
+					be retried.  This applies both within
+					a single queue run and to persistent
+					information (see below).
+confTO_RESOLVER_RETRANS	Timeout.resolver.retrans
+					[varies] Sets the resolver's
+					retransmition time interval (in
+					seconds).  Sets both
+					Timeout.resolver.retrans.first and
+					Timeout.resolver.retrans.normal.

+					message.
+confTO_RESOLVER_RETRY_NORMAL  Timeout.resolver.retry.normal
+					[varies] Sets the number of times
+					to retransmit a resolver query for
+					all resolver lookups except the
+					first delivery attempt.
+confTIME_ZONE		TimeZoneSpec	[USE_SYSTEM] Time zone info -- can be
+					USE_SYSTEM to use the system's idea,
+					USE_TZ to use the user's TZ envariable,
+					or something else to force that value.
+confDEF_USER_ID		DefaultUser	[1:1] Default user id.
+confUSERDB_SPEC		UserDatabaseSpec
+					[undefined] User database
+					specification.
+confFALLBACK_MX		FallbackMXhost	[undefined] Fallback MX host.
+confTRY_NULL_MX_LIST	TryNullMXList	[False] If this host is the best MX
+					for a host and other arrangements
+					haven't been made, try connecting
+					to the host directly; normally this
+					would be a config error.
+confQUEUE_LA		QueueLA		[varies] Load average at which
+					queue-only function kicks in.
+					Default values is (8 * numproc)
+					where numproc is the number of
+					processors online (if that can be
+					determined).
+confREFUSE_LA		RefuseLA	[varies] Load average at which
+					incoming SMTP connections are
+					refused.  Default values is (12 *
+					numproc) where numproc is the
+					number of processors online (if
+					that can be determined).
+confMAX_ALIAS_RECURSION	MaxAliasRecursion
+					[10] Maximum depth of alias recursion.
+confMAX_DAEMON_CHILDREN	MaxDaemonChildren
+					[undefined] The maximum number of
+					children the daemon will permit.  After
+					this number, connections will be
+					rejected.  If not set or <= 0, there is
+					no limit.
+confMAX_HEADERS_LENGTH	MaxHeadersLength
+					[undefined] Maximum length of the sum
+					of all headers.
+confMAX_MIME_HEADER_LENGTH  MaxMimeHeaderLength
+					[undefined] Maximum length of
+					certain MIME header field values.
+confCONNECTION_RATE_THROTTLE ConnectionRateThrottle
+					[undefined] The maximum number of
+					connections permitted per second.
+					After this many connections are
+					accepted, further connections will be
+					delayed.  If not set or <= 0, there is
+					no limit.
+confWORK_RECIPIENT_FACTOR
+			RecipientFactor	[30000] Cost of each recipient.
+confSEPARATE_PROC	ForkEachJob	[False] Run all deliveries in a
+					separate process.
+confWORK_CLASS_FACTOR	ClassFactor	[1800] Priority multiplier for class.
+confWORK_TIME_FACTOR	RetryFactor	[90000] Cost of each delivery attempt.
+confQUEUE_SORT_ORDER	QueueSortOrder	[Priority] Queue sort algorithm:
+					Priority, Host, Filename, or Time.
+confMIN_QUEUE_AGE	MinQueueAge	[0] The minimum amount of time a job
+					must sit in the queue between queue
+					runs.  This allows you to set the
+					queue run interval low for better
+					responsiveness without trying all
+					jobs in each run.
+confDEF_CHAR_SET	DefaultCharSet	[unknown-8bit] When converting
+					unlabeled 8 bit input to MIME, the
+					character set to use by default.
+confSERVICE_SWITCH_FILE	ServiceSwitchFile
+					[/etc/mail/service.switch] The file
+					to use for the service switch on
+					systems that do not have a
+					system-defined switch.
+confHOSTS_FILE		HostsFile	[/etc/hosts] The file to use when doing
+					"file" type access of hosts names.
+confDIAL_DELAY		DialDelay	[0s] If a connection fails, wait this
+					long and try again.  Zero means "don't
+					retry".  This is to allow "dial on
+					demand" connections to have enough time
+					to complete a connection.
+confNO_RCPT_ACTION	NoRecipientAction
+					[none] What to do if there are no legal
+					recipient fields (To:, Cc: or Bcc:)
+					in the message.  Legal values can
+					be "none" to just leave the
+					nonconforming message as is, "add-to"
+					to add a To: header with all the
+					known recipients (which may expose
+					blind recipients), "add-apparently-to"
+					to do the same but use Apparently-To:
+					instead of To:, "add-bcc" to add an
+					empty Bcc: header, or
+					"add-to-undisclosed" to add the header
+					``To: undisclosed-recipients:;''.
+confSAFE_FILE_ENV	SafeFileEnvironment
+					[undefined] If set, sendmail will do a
+					chroot() into this directory before
+					writing files.
+confCOLON_OK_IN_ADDR	ColonOkInAddr	[True unless Configuration Level > 6]
+					If set, colons are treated as a regular
+					character in addresses.  If not set,
+					they are treated as the introducer to
+					the RFC 822 "group" syntax.  Colons are
+					handled properly in route-addrs.  This
+					option defaults on for V5 and lower
+					configuration files.
+confMAX_QUEUE_RUN_SIZE	MaxQueueRunSize	[0] If set, limit the maximum size of
+					any given queue run to this number of
+					entries.  Essentially, this will stop
+					reading each queue directory after this
+					number of entries are reached; it does
+					_not_ pick the highest priority jobs,
+					so this should be as large as your
+					system can tolerate.  If not set, there
+					is no limit.
+confDONT_EXPAND_CNAMES	DontExpandCnames
+					[False] If set, $[ ... $] lookups that
+					do DNS based lookups do not expand
+					CNAME records.  This currently violates
+					the published standards, but the IETF
+					seems to be moving toward legalizing
+					this.  For example, if "FTP.Foo.ORG"
+					is a CNAME for "Cruft.Foo.ORG", then
+					with this option set a lookup of
+					"FTP" will return "FTP.Foo.ORG"; if
+					clear it returns "Cruft.FOO.ORG".  N.B.
+					you may not see any effect until your
+					downstream neighbors stop doing CNAME
+					lookups as well.
+confFROM_LINE		UnixFromLine	[From $g $d] The From_ line used
+					when sending to files or programs.
+confSINGLE_LINE_FROM_HEADER  SingleLineFromHeader
+					[False] From: lines that have
+					embedded newlines are unwrapped
+					onto one line.
+confALLOW_BOGUS_HELO	AllowBogusHELO	[False] Allow HELO SMTP command that
+					does not include a host name.
+confMUST_QUOTE_CHARS	MustQuoteChars	[.'] Characters to be quoted in a full
+					name phrase (@,;:\()[] are automatic).
+confOPERATORS		OperatorChars	[.:%@!^/[]+] Address operator
+					characters.
+confSMTP_LOGIN_MSG	SmtpGreetingMessage
+					[$j Sendmail $v/$Z; $b]
+					The initial (spontaneous) SMTP
+					greeting message.  The word "ESMTP"
+					will be inserted between the first and
+					second words to convince other
+					sendmails to try to speak ESMTP.
+confDONT_INIT_GROUPS	DontInitGroups	[False] If set, the initgroups(3)
+					routine will never be invoked.  You
+					might want to do this if you are
+					running NIS and you have a large group
+					map, since this call does a sequential
+					scan of the map; in a large site this
+					can cause your ypserv to run
+					essentially full time.  If you set
+					this, agents run on behalf of users
+					will only have their primary
+					(/etc/passwd) group permissions.
+confUNSAFE_GROUP_WRITES	UnsafeGroupWrites
+					[False] If set, group-writable
+					:include: and .forward files are
+					considered "unsafe", that is, programs
+					and files cannot be directly referenced
+					from such files.  World-writable files
+					are always considered unsafe.
+confCONNECT_ONLY_TO	ConnectOnlyTo	[undefined] override connection
+					address (for testing).
+confCONTROL_SOCKET_NAME	ControlSocketName
+					[undefined] Control socket for daemon
+					management.
+confDOUBLE_BOUNCE_ADDRESS  DoubleBounceAddress
+					[postmaster] If an error occurs when
+					sending an error message, send that
+					"double bounce" error message to this
+					address.
+confDEAD_LETTER_DROP	DeadLetterDrop	[undefined] Filename to save bounce
+					messages which could not be returned
+					to the user or sent to postmaster.
+					If not set, the queue file will
+					be renamed.
+confRRT_IMPLIES_DSN	RrtImpliesDsn	[False] Return-Receipt-To: header
+					implies DSN request.
+confRUN_AS_USER		RunAsUser	[undefined] If set, become this user
+					when reading and delivering mail.
+					Causes all file reads (e.g., .forward
+					and :include: files) to be done as
+					this user.  Also, all programs will
+					be run as this user, and all output
+					files will be written as this user.
+					Intended for use only on firewalls
+					where users do not have accounts.
+confMAX_RCPTS_PER_MESSAGE  MaxRecipientsPerMessage
+					[infinite] If set, allow no more than
+					the specified number of recipients in
+					an SMTP envelope.  Further recipients
+					receive a 452 error code (i.e., they
+					are deferred for the next delivery
+					attempt).
+confDONT_PROBE_INTERFACES  DontProbeInterfaces
+					[False] If set, sendmail will _not_
+					insert the names and addresses of any
+					local interfaces into the $=w class
+					(list of known "equivalent" addresses).
+					If you set this, you must also include
+					some support for these addresses (e.g.,
+					in a mailertable entry) -- otherwise,
+					mail to addresses in this list will
+					bounce with a configuration error.
+confPID_FILE		PidFile		[system dependent] Location of pid
+					file.
+confPROCESS_TITLE_PREFIX  ProcessTitlePrefix
+					[undefined] Prefix string for the
+					process title shown on 'ps' listings.
+confDONT_BLAME_SENDMAIL	DontBlameSendmail
+					[safe] Override sendmail's file
+					safety checks.  This will definitely
+					compromise system security and should
+					not be used unless absolutely
+					necessary.
+confREJECT_MSG		-		[550 Access denied] The message
+					given if the access database contains
+					REJECT in the value portion.
+confDF_BUFFER_SIZE	DataFileBufferSize
+					[4096] The maximum size of a
+					memory-buffered data (df) file
+					before a disk-based file is used.
+confXF_BUFFER_SIZE	XScriptFileBufferSize
+					[4096] The maximum size of a
+					memory-buffered transcript (xf)
+					file before a disk-based file is
+					used.
+confAUTH_MECHANISMS	AuthMechanisms	[GSSAPI KERBEROS_V4 DIGEST-MD5
+					CRAM-MD5] List of authentication
+					mechanisms for AUTH (separated by
+					spaces).  The advertised list of
+					authentication mechanisms will be the
+					intersection of this list and the list
+					of available mechanisms as determined
+					by the CYRUS SASL library.
+confDEF_AUTH_INFO	DefaultAuthInfo	[undefined] Filename that contains
+					authentication information for
+					outgoing connections.  This file
+					must contain the user id, the
+					authorization id, the password
+					(plain text), and the realm to
+					use on separate lines and must be
+					readable by root (or the trusted
+					user) only.  If no realm is
+					specified, $j is used.
+confAUTH_OPTIONS	AuthOptions	[undefined] If this options is 'A'
+					then the AUTH= parameter for the
+					MAIL FROM command is only issued
+					when authentication succeeded.
+confLDAP_DEFAULT_SPEC	LDAPDefaultSpec	[undefined] Default map
+					specification for LDAP maps.  The
+					value should only contain LDAP
+					specific settings such as "-h host
+					-p port -d bindDN", etc.  The
+					settings will be used for all LDAP
+					maps unless they are specified in
+					the individual map specification
+					('K' command).
+
+See also the description of OSTYPE for some parameters that can be
+tweaked (generally pathnames to mailers).
+
+DaemonPortOptions are a special case since multiple daemons can be
+defined.  This can be done via
+
+	DAEMON_OPTIONS(`field1=value1,field2=value2,...')
+
+If DAEMON_OPTIONS is not used, then the default is
+
+	DAEMON_OPTIONS(`Port=smtp, Name=MTA')
+	DAEMON_OPTIONS(`Port=587, Name=MSA, M=E')
+
+If you use one DAEMON_OPTIONS macro, it will alter the parameters
+of the first of these.  The second will still be defaulted; it
+represents a "Message Submission Agent" (MSA) as defined by RFC
+2476 (see below).  To turn off the default definition for the MSA,
+use FEATURE(`no_default_msa') (see also FEATURES).  If you use
+additional DAEMON_OPTIONS macros, they will add additional daemons.
+
+Example 1:  To change the port for the SMTP listener, while
+still using the MSA default, use
+	DAEMON_OPTIONS(`Port=925, Name=MTA')
+
+Example 2:  To change the port for the MSA daemon, while still
+using the default SMTP port, use
+	FEATURE(`no_default_msa')
+	DAEMON_OPTIONS(`Name=MTA')
+	DAEMON_OPTIONS(`Port=987, Name=MSA, M=E')
+
+Note that if the first of those DAEMON_OPTIONS lines were omitted, then
+there would be no listener on the standard SMTP port.
+
+A "Message Submission Agent" still uses all of the same rulesets for
+processing the message (and therefore still allows message rejection via
+the check_* rulesets).  In accordance with the RFC, the MSA will ensure
+that all domains in the envelope are fully qualified if the message is
+relayed to another MTA.  It will also enforce the normal address syntax
+rules and log error messages.  Additionally, by using the M=a modifier
+you can require authentication before messages are accepted by the MSA.
+Finally, the M=E modifier shown above disables ETRN as required by RFC
+2476.
+
+
++-----------+
+| HIERARCHY |
++-----------+
+
+Within this directory are several subdirectories, to wit:
+
+m4		General support routines.  These are typically
+		very important and should not be changed without
+		very careful consideration.
+
+cf		The configuration files themselves.  They have
+		".mc" suffixes, and must be run through m4 to
+		become complete.  The resulting output should
+		have a ".cf" suffix.
+
+ostype		Definitions describing a particular operating
+		system type.  These should always be referenced
+		using the OSTYPE macro in the .mc file.  Examples
+		include "bsd4.3", "bsd4.4", "sunos3.5", and
+		"sunos4.1".
+
+domain		Definitions describing a particular domain, referenced
+		using the DOMAIN macro in the .mc file.  These are
+		site dependent; for example, "CS.Berkeley.EDU.m4"
+		describes hosts in the CS.Berkeley.EDU subdomain.
+
+mailer		Descriptions of mailers.   These are referenced using
+		the MAILER macro in the .mc file.
+
+sh		Shell files used when building the .cf file from the
+		.mc file in the cf subdirectory.
+
+feature		These hold special orthogonal features that you might
+		want to include.  They should be referenced using
+		the FEATURE macro.
+
+hack		Local hacks.  These can be referenced using the HACK
+		macro.  They shouldn't be of more than voyeuristic
+		interest outside the .Berkeley.EDU domain, but who knows?
+
+siteconfig	Site configuration -- e.g., tables of locally connected
+		UUCP sites.
+
+
++------------------------+
+| ADMINISTRATIVE DETAILS |
++------------------------+
+
+The following sections detail usage of certain internal parts of the
+sendmail.cf file.  Read them carefully if you are trying to modify
+the current model.  If you find the above descriptions adequate, these
+should be {boring, confusing, tedious, ridiculous} (pick one or more).
