# smtpd and smtpfwdd generate lots of syslogs, by design.
#
# What log facility should smtpd and smtpfwdd use for syslogs? The
# default is LOG_MAIL, which is also used by critters like sendmail.
# if you don't like this and want the logs going elsewhere for easy

# your /etc/syslog.conf file to deal with it to your liking.

# Should smtpfwdd check the exit code of sendmail? smtpfwdd checks any
# non-zero exit status from sendmail to see if it indicates that
# sendmail thinks the message might be deliverable later. Normally
# this should not be a problem, however if you are not running
# sendmail as your delivery agent, or if your sendmail is broken, the
# exit codes may not mean much. In such a case you may not want
# smtpfwdd to retry message delivery when the mta exits indicating a
# failure. Setting SENDMAIL_RETRY to 0 below will make sure smtpfwdd
# never retries delivery if the MTA returns a non-zero exit
# status. You probably shouldn't change this unless you are sure you
# know what you are doing.

# Sendmail has a feature/bug that when feeding a message to it it will
# stop if a line contains only a '.'. This is suppressed in smtpfwdd
# by invoking sendmail with the "-oiTrue" option if the mail agent's

# How many arguments can your execv() call take at once? This can be a
# conservative estimate. It determines the maximum number of
# recipients at a time that MAIL_AGENT will be invoked with by
# smtpfwdd. 
# N.B. MAXARGS must be at least 6, or 5 if SENDMAIL_OITRUE (above) is 1.

# Smtpd's default informational status messages in the smtp dialogue
# are somewhat unique and interesting (see smtpd.h). Normally these
# are only seen by people telnetting to your smtp port, or debugging
# mail.  While the author has no shame and won't change the default
# It's understandable that they aren't everyone's cup of tea. Set
# VANILLA_MESSAGES below to 1 and smtp will use plain old politically
# correct Sendmail/RFC 821 style status messages.

# smtpd checks and clobbers and potentially "evil" characters in hostnames,
# and mail addresses recieved on FROM: and RCPT: lines. This clobbers things
# like a connection from hostname `/bin/rm -rf /`@evil.org, or mail to
# "| /bin/sh". It also clobbers things like 8bit chars in such things.
# smtpd always clobbers the characters it doesn't like, 
# and syslogs a note of the fact. The options below determine whether or
# not smtpd will also drop the connection.
#
# Beware of setting this to 1 if your receive mail from sites where
# it's considered ok to put 8 bit ascii chars in message headers. 
# 
# If PARANOID_SMTP is 1, smtpd will close connection on any client
# that puts characters it thinks may be evil in the smtp dialogue, 
# (HELO, FROM, RCPT), or in the message headers. 
# When PARANOID_SMTP is 0, smtpd will replace the characters it thinks
# are evil and continue. 
# PARANOID_SMTP = 1

# If PARANOID_DNS is 1, smtpd will close connection on any client that
# has characters it thinks may be evil in it's hostname as found by DNS,
# or any client whose DNS forward and reverse mappings are inconsistent
# indicating a DNS spoof of misconfiguration.
# If PARANOID_DNS is 0, smtpd will replace any evil characters it sees
# continue.

# The check above will clobber stuff in the headers from some
# non north-american localizations.
# If your operating system has localization support
# you can define LOCALIZATION below to be your localization.
# For this to work, your operating system must support localization
# with setlocale, and you must copy the appropriate localization
# files into the right place in smtpd's chroot directory.
# The result of this is that smtpd will use a 
# setlocale(LC_CTYPE, LOCALIZATION) to hopefully make sure
# your normal stuff won't get clobbered.
# Leave this set to 0 for no localization support.

# Smtpd does not support ESMTP's EHLO command normally, as it shouldn't
# need to. According to RFC, if the EHLO is unrecognized the connecting
# agent should drop back to a HELO on the second attempt (and then be
# talking vanilla smtp). Unfortunately Netscape Communicator betas seem
# seem to have a bug in which they simply try the EHLO again. Sigh. 
# setting EHLO_KLUDGE to 1 will make smtpd accept a second EHLO as a helo, 
# thereby kludging around this bug in Communicator. 
#EHLO_KLUDGE=1

# smtpd can check FROM and RCPT addresses, along with the connecting
# host info using an address check file. This can be used to only
# allow certain mail addresses on a FROM:, or certain combinations of
# FROM: and RCPT from certain hosts. It can be used to prevent third
# party relays, enforce outgoing address conventions, prevent outgoing
# SPAM/obvious forgeries, or block incoming SPAM. Setting this to 0 will
# mean that none of the address checking functionality is compiled in at
# all. (meaning all of address_check.c is #ifdefed out).  
CHECK_ADDRESS = 1
# CHECK_ADDRESS = 0

# Set This to 1 if you are running smtpd on a Juniper firewall machine.
# This enables smtpd to use juniper's trusted/untrusted interface
# mechanism, allowing you to use the UNTRUSTED or TRUSTED specials
# in address check rules to match based on what kind of interface
# a connection arrived on.
#
# You must set this to 0 this on a non-juniper machine or smtpd will not
# build with CHECK_ADDRESS set to 1. You will get an error about
# juniper_firewall.h not existing if you forget this.

JUNIPER_SUPPORT=0

# Use regexp's in patterns?  If you have a POSIX <regex.h> and friends, 
# and you trust the regex lib enough for use, you can set USE_REGEX to 
# 1, this allows you to specify a pattern enclosed in "/" as a regular
# POSIX/henry-spencer style extended regex for case insensitive matching
# (what's between the "/" gets fed to regcomp with 
# REG_EXTENDED|REG_ICASE|REG_NOSUB options, then matched against) 
#
# Note that older beasts (like SunOS 4.X) usually don't have a regex
# library, so if you're using something that doesn't you should set this
# to 0.
#
#USE_REGEX=0
USE_REGEX=1

# Enable checking namservers?  with NS_MATCH set to 1, patterns of the
# form NS=pattern can be used to match rules against the nameservers
# and MX records of originating connections or mail addresses, rather
# than the connection itself. This allows for small rules to block out
# whole blocks of bozos from rogue providers such as ispam.net should
# you choose to do so. i.e.
#
#noto_delay:NS=205.199.212.0/24 NS=205.199.2.0/24 NS=207.124.161.0/24:ALL:ALL
#noto_delay:ALL:NS=205.199.212.0/24 NS=205.199.2.0/24 NS=207.124.161.0/24:ALL
#
# would effectively block off anything originiating from, or with a FROM:
# address looking like any of it's nameservers are on one of cyberpromo.com's
# addresses. 
#
# uncomment the LD_LIBS line as well if you enable NS_MATCH unless your 
# resolver routines are in libc (like they are on some Linuxes)
#
# The NS_MATCH feature is lovingly dedicated by Bob Beck to Spamford
# Wallace and ispam.net
#
#NS_MATCH=0
NS_MATCH=1
LD_LIBS+=-lresolv  # you may or may not need this.

# The rules file for address checking, if enabled, remember this file
# will be in the chroot jail, so the line below probably means
# /usr/spool/smtpd/etc/smtpd_check_rules, unless you changed the
# chroot directory above.
CHECK_FILE = /etc/smtpd_check_rules

# address checking rules may want user information, gotten from an RFC
# 931 style ident. This info may be passed in the environment to smtpd
# (from juniperd or the tcp wrapper), or smtpd will do the ident
# request itself if required.  CHECK_IDENT determines the timeout (in
# seconds) on an ident request.  if CHECK_IDENT is 0, no ident
# requests will be made by smtpd even if it sees a rule that would
# normally make it perform one.  
# CHECK_IDENT = 0 
CHECK_IDENT = 10

# If you use the address checks to block incoming mail from certain
# spam sites, you can set NOTO_DELAY and DENY_DELAY below to specify
# the time in seconds smtpd will go to sleep for after matching a
# "noto_delay" or "deny_delay" rule.  This makes your site a small
# headache to the spammer since they have to wait before being denied,
# instead of immediately knowing so, and proceeding on to their next
# victim.
# NOTO_DELAY = 0
# DENY_DELAY = 0 
# NOTO_DELAY = 300
# DENY_DELAY = 300
NOTO_DELAY = 50
DENY_DELAY = 50

# Because CHECK_ADDRESS above is meant to be used as a nuisance filter
# the default is to ALLOW on failure rather than deny service when no
# match is found, or if something happens while attempting to match a
# rule (such as a system call failure, or you make a syntax error in the
# rules file). Change
# CHECK_ADDRESS_DENY_ON_FAILURE to 1 to have smtpd not allow anything
# not explicitly allowed by the rules.
# CHECK_ADDRESS_DENY_ON_FAILURE = 1
