-------------------------------------------------------------------------------
X
1. Introduction
---------------
X
These tools may be of use to those sites using sendmail. Both are written in
Perl. Our site, Mot.COM, receives a ton of mail being a top-level domain
gateway. We have over 24 domains under us. Needless to say, we must have
a robust mail system or my head, and others, would be on the chopping block.
X
2. Description
--------------
X
The first tool, cqueue, checks the sendmail queue for problems. We use
it to flag problems with subdomain mail servers (and even our own servers
once in a while ;-). We run it via a cron job every hour during the day.
You may find this too frequent, however. 
X
The other program, postclip, is used to "filter" non-deliverable NDNs that
get sent to our Postmaster account now and then. This ensures privacy of
e-mail and helps avoid disk problems from huge NDNs. It is different than
a brute force "just keep the header" approach because it tries hard to keep
other parts of the message that look like non-delivery information.
X
Both have been used for some time at our site with no problems. Everything 
you need should be in this distribution: source, manual pages, and support 
libs. See the manual pages for a complete description of each tool.
X
3. Installation
---------------
X
No fancy Makefile simply because these tools are all under a large
hierarchy at my site. Installation should be a snap, however. Install
the nroff(1) man(5) manual pages from the man subdirectory to the
appropriate directory on your system. This might be something like
/usr/local/man/man1.
X
Next, install all of the Perl libraries located in the lib subdirectory
to your Perl library area. /usr/local/lib/perl is a good bet. The person
who installed Perl at your site will be able to tell you for sure. 
X
Finally, you need to install the programs. Note that cqueue wants to
run setuid root by default. This is because the sendmail queue is normally
only readable by root or some special group. In order to let any user
run this suidperl is used. suidperl allows a Perl program to run with the
privileges of another user. 
X
You will have to edit both the cqueue and postclip programs to change
the #! line at the top of each. Just change the pathname to whatever is
appropriate on your system. Note that Larry Wall's fixin program from
the Camel book can also be used to do this. It is very handy. It changes
#! lines by looking at your PATH.
X
If you do not have suidperl on your system change the #! line in cqueue
to reference perl instead of suidperl.
X
You may also wish to change some constants in cqueue. $DEF_QUEUE should be
changed to your queue directory if it is not /usr/spool/mqueue. $DEF_TIME
could be changed easy enough also. It is the time spec for the time duration
after which a mail message will be reported on if the -a option has not been
specified. See the manual page for more information and the format of this
constant (same as the -t argument). Then again, neither of these has to
be changed. Command line options are there to override their default
values.
X
After you have edited the programs as necessary, all that remains is to
install them to some executable directory. Install postclip mode 555
and cqueue mode 4555 with owner root (if using suidperl) or mode 555
(if not using suidperl).
X
4. Gripes, Comments, Etc
------------------------
X
If you start using either of these let me know. I have other mail tools I
will likely post in the future if these prove useful. Also, if you think
something is just plain dumb/wrong/stupid let me know!
X
Cheers,
-Mike

;# Name
;#	date.pl - Perl emulation of (the output side of) date(1)
;#
;# Synopsis
;#	require "date.pl";
;#	$Date = &date(time);
;#	$Date = &date(time, $format);
;#
;# Description
;#	This package implements the output formatting functions of date(1) in
;#	Perl.  The format options are based on those supported by Ultrix 4.0
;#	plus a couple of additions from SunOS 4.1.1 and elsewhere:
;#
;#		%a		abbreviated weekday name - Sun to Sat
;#		%A		full weekday name - Sunday to Saturday
;#		%b		abbreviated month name - Jan to Dec
;#		%B		full month name - January to December
;#		%c		date and time in local format [+]
;#		%C		date and time in long local format [+]
;#		%d		day of month - 01 to 31
;#		%D		date as mm/dd/yy
;#		%e		day of month (space padded) - ` 1' to `31'
;#		%E		day of month (with suffix: 1st, 2nd, 3rd...)
;#		%f		month of year (space padded) - ` 1' to `12'
;#		%h		abbreviated month name - Jan to Dec
;#		%H		hour - 00 to 23
;#		%i		hour (space padded) - ` 1' to `12'
;#		%I		hour - 01 to 12
;#		%j		day of the year (Julian date) - 001 to 366
;#		%k		hour (space padded) - ` 0' to `23'
;#		%l		date in ls(1) format
;#		%m		month of year - 01 to 12
;#		%M		minute - 00 to 59
;#		%n		insert a newline character
;#		%p		ante-meridiem or post-meridiem indicator (AM or PM)
;#		%r		time in AM/PM notation
;#		%R		time as HH:MM
;#		%S		second - 00 to 59
;#		%t		insert a tab character
;#		%T		time as HH:MM:SS
;#		%u		date/time in date(1) required format
;#		%U		week number, Sunday as first day of week - 00 to 53
;#		%V		date-time in SysV touch format (mmddHHMMyy)
;#		%w		day of week - 0 (Sunday) to 6
;#		%W		week number, Monday as first day of week - 00 to 53
;#		%x		date in local format [+]
;#		%X		time in local format [+]
;#		%y		last 2 digits of year - 00 to 99
;#		%Y		all 4 digits of year ~ 1700 to 2000 odd ?
;#		%z		time zone from TZ environment variable w/ a trailing space
;#		%Z		time zone from TZ environment variable
;#		%%		insert a `%' character
;#		%+		insert a `+' character
;#
;#	[+]:  These may need adjustment to fit local conventions, see below.
;#
;#	For the sake of compatibility, a leading `+' in the format
;#	specificaiton is removed if present.
;#
;# Remarks
;#	This is version 3.4 of date.pl
;#
;#	An extension of `ctime.pl' by Waldemar Kebsch (kebsch.pad@nixpbe.UUCP),
;#	as modified by Marion Hakanson (hakanson@ogicse.ogi.edu).
;#
;#  Unlike date(1), unknown format tags are silently replaced by "".
;#
;#  defaultTZ is a blatant hack, but I wanted to be able to get date(1)
;#	like behaviour by default and there does'nt seem to be an easy (read
;#	portable) way to get the local TZ name back...
;#
;#	For a cheap date, try...
;#
;#		#!/usr/local/bin/perl
;#		require "date.pl";
;#		exit print (&date(time, shift @ARGV) . "\n") ? 0 : 1;
;#
;#	This package is redistributable under the same terms as apply to
;#	the Perl 4.0 release.  See the COPYING file in your Perl kit for
;#	more information.

;# Modification History
;#	Nmemonic	Version	Date		Who
;#
;#	NONE		1.0		02feb91		Terry McGonigal (tmcgonigal@gallium.com)
;#		Created from ctime.pl
;#
;#	NONE		2.0		07feb91		tmcgonigal
;#		Added some of Marion Hakanson (hakanson@ogicse.ogi.edu)'s ctime.pl
;#		TZ handling changes.
;#
;#	NONE		2.1		09feb91		tmcgonigal
;#		Corrected week number calculations.
;#
;#	NONE		2.2		21oct91		tmcgonigal
;#		Added ls(1) date format, `%l'.
;#
;#	NONE		2.3		06nov91		tmcgonigal
;#		Added SysV touch(1) date-time format, `%V' (pretty thin as
;#		mnemonics go, I know, but `t' and `T' were both gone already!)
;#
;#	NONE		2.4		05jan92		tmcgonigal
;#		Corrected slight (cosmetic) problem with %V replacment string
;#
;#	NONE		3.0		09jul92		tmcgonigal
;#		Fixed a couple of problems with &ls as pointed out by
;#		Thomas Richter (richter@ki1.chemie.fu-berlin.de), thanks Thomas!
;#		Also added a couple of SunOS 4.1.1 strftime-ish formats, %i and %k
;#		for space padded hours (` 1' to `12' and ` 0' to `23' respectivly),
;#		and %C for locale long date/time format.  Changed &ampmH to take a
;#		pad char parameter to make to evaled code for %i and %k simpler. 
;#		Added %E for suffixed day-of-month (ie 1st, 3rd, 4th etc).
;#
;#	NONE		3.1		16jul92		tmcgonigal
;#		Added `%u' format to generate date/time in date(1) required
;#		format (ie '%y%m%d%H%M.%S').
;#
;#	NONE		3.2		23jan93		tmcgonigal
;#		Added `%f' format to generate space padded month numbers, added
;#		`%E' to the header comments, it seems to have been left out (and
;#		I'm sure I wanted to use it at some point in the past...).
;#
;#	NONE		3.3		03feb93		tmcgonigal
;#		Corrected some problems with AM/PM handling pointed out by
;#		Michael S. Muegel (mmuegel@mot.com).  Thanks Michael, I hope
;#		this is the behaviour you were looking for, it seems more
;#		correct to me...
;#
;#	NONE		3.4		26jul93		tmcgonigal
;#		Incorporated some fixes provided by DaviD W. Sanderson
;#		(dws@ssec.wisc.edu): February was spelled incorrectly and
;#		&wkno() was always using the current year while calculating
;#		week numbers, regardless of year implied by the time value
;#		passed to &date().  DaviD also contributed an improved &date()
;#		test script, thanks DaviD, I appreciate the effort.  Finally,
;#		changed my mailling address from @gvc.com to @gallium.com
;#		to reflect, well, my new address!

;# Sends $Message to $Users with a subject of $Subject. If $Message_Is_File

;#
;# If everything went OK $Status will be 1 and $Error_Msg can be ignored; 
;# otherwise, $Status will be 0 and $Error_Msg will contain an error message.
;# 
;# If $Use_Sendmail is 1 then sendmail is used to send the message. Normally
;# a mailer such as Mail is used. By specifiying this you can include 
;# headers in addition to text in either $Message or $Message_Is_File.
;# If either $Message or $Message_Is_File contain a Subject: header then
;# $Subject is ignored; otherwise, a Subject: header is automatically created.
;# Similar to the Subject: header, if a To: header does not exist one
;# is automatically created from the $Users argument. The mail is still
;# sent, however, to the recipients listed in $Users. This is keeping with
;# normal sendmail usage (header vs. envelope).
;# 
;# In both bin mailer and sendmail modes $Verbose will turn on verbose mode
;# (normally just sendmail verbose mode output).

;# New_Getopts
;#
;# Does not care about order of switches, options, and arguments like 
;# getopts.pl. Thus all non-switches/options will be kept in ARGV even if they
;# are not at the end. If $Pass_Invalid is set all unkown options will be
;# passed back to the caller by keeping them in @ARGV. This is useful when
;# parsing a command line for your script while ignoring options that you
;# may pass to another script. If this is set New_Getopts tries to maintain 
;# the switch clustering on the unkown switches.
;#
;# Accepts the special argument -usage to print the Usage string. Also accepts 
;# the special option -version which prints the contents of the string 
;# $VERSION. $VERSION may or may not have an embeded \n in it. If -usage 
;# or -version are specified a status of -1 is returned. Note that the usage
;# option is only accepted if the usage string is not null.
;# 
;# $Switches is just like the formal arguemnt of getopts.pl. $Usage is a usage
;# string with or without a trailing \n. *Switch_To_Order is an optional
;# pointer to the name of an associative array which will contain a mapping of
;# switch names to the order in which (if at all) the argument was entered.
;#
;# For example, if @ARGV contains -v, -x, test:
;#
;#    $Switch_To_Order {"v"} = 1;
;#    $Switch_To_Order {"x"} = 2;
;#
;# Note that in the case of multiple occurances of an option $Switch_To_Order
;# will store each occurance of the argument via a string that emulates
;# an array. This is done by using join ($;, ...). You can retrieve the
;# array by using split (/$;/, ...).
;#
;# *Split_ARGV is an optional pointer to an array which will conatin the
;# original switches along with their values. For the example used above 
;# Split_ARGV would contain:
;#
;#   @Split_ARGV = ("v", "", "x", "test");
;#
;# Another exciting ;-) feature that newgetopts has. Along with creating the 
;# normal $opt_ scalars for the last value of an argument the list @opt_ is 
;# created. It is an array which contains all the values of arguments to the 
;# basename of the variable. They are stored in the order which they occured 
;# on the command line starting with $[. Note that blank arguments are stored 
;# as "". Along with providing support for multiple options on the command 
;# line this also provides a method of counting the number of times an option 
;# was specified via $#opt_.
;#
;# Automatically resets all $opt_, @opt_, %Switch_To_Order, and @Split_ARGV
;# variables so that New_Getopts may be called more than once from within
;# the same program. Thus, if $opt_v is set upon entry to New_Getopts and 
;# -v is not in @ARGV $opt_v will not be set upon exit.
;#
;# Arguments:
;#    $Switches, $Usage, $Pass_Invalid, *Switch_To_Order, *Split_ARGV
;#
;# Returns:
;#    -1, 0, or 1 depending on status (printed Usage/Version, OK, not OK)

;# Format_Text_Block
;#
;# Formats a text string to be printed to the display or other similar device.
;# Text in $String will be fomratted such that the following hold:
;#
;#    + $String contains the (possibly) multi-line text to print. It is
;#	automatically word-wrapped to fit in $Columns. 
;#
;#    + \n'd are maintained and are not folded.
;#
;#    + $Offset	is pre-pended before each separate line of text. 
;#
;#    + If $Offset_Once	is $TRUE $Offset will only appear on the first line.
;#      All other lines will be indented to match the amount of whitespace of
;#      $Offset.
;#
;#    + If $Bullet_Indent is $TRUE $Offset will only be applied to the begining
;#      of lines as they occured in the original $String. Lines that are created
;#      by this routine will always be indented by blank spaces.
;#
;#    + If $Columns is 0 no word-wrap is done. This might be useful to still
;#      to offset each line in a buffer.
;#
;#    + If $Split_Expr is supplied the string is split on it. If not supplied
;#      the string is split on " \t\/\-\,\." by default.
;#
;#    + If $Offset_Blank is $TRUE then empty lines will have $Offset pre-pended
;#      to them. Otherwise, they will still empty.
;#
;# This is a realy workhorse routine that I use in many places because of its
;# veratility.

.SH NAME
\*(mp - check sendmail queue for problems
.SH SYNOPSIS
.IP \*(mp 7 
[ \fB-abdms\fR ] [ \fB-q\fR \fIqueue-dir\fI ] [ \fB-t\fR \fItime\fR ] 
[ \fB-u\fR \fIusers\fR ] [ \fB-w\fR \fIwidth\fR ]
.SH DESCRIPTION
Reports on problems in the sendmail queue. With no options this simply
means listing messages that have been in the queue longer than a default
period along with a summary of queue mail by host and status message.
.SH OPTIONS
.IP \fB-a\fR 14
Report on all messages in the queue. This is equivalent to saying \fB-t\fR 0s.
You may like this command so much that you use it as a replacement for
\fBmqueue\fR. For example:
.sp 1
.RS
.RS
\fBalias mqueue cqueue -a\fR
.RE
.RE
.IP \fB-b\fR 14
Also report on bogus queue files. Those are files that
have data files and no control files or vice versa.
.IP \fB-d\fR
Print a detailed report of mail messages that have been queued longer than
the specified or default time. Information that is presented includes:
.RS
.RS
.IB
Sendmail queue identifier.
.IB
Date the message was first queued.
.IB
Sender of the message.
.IB
One or more recipients of the message.
.IB
An optional status of the message. This usually indicates why the message
has not been delivered.
.RE
.RE
.IP \fB-m\fR 14
Mail off the results if any problems were found.
Normaly results are printed to stdout. If this option
is specified they are mailed to one or more users. Results
are not printed to stdout in this case. Results are \fBonly\fR
mailed if \*(mp found something wrong.
.IP "\fB-q\fR \fIqueue-dir\fI"
The sendmail mail queue directory. Default is \fB/usr/spool/mqueue\fR or
some other site configured value.
.IP "\fB-t\fR \fItime\fR"
List messages that have been in the queue longer than
\fItime\fR. Time should of the form:
.sp 1
.RS
.RS
(<number>(s|m|h|d))+
.sp 1
.RE
.RE
.RS 14
The second portion of the above definition
specifies seconds, minutes, hours, or
days, respectfully. The first portion is the number of
those units. There can be any number of such specifiers.
As an example, 1h30m means 1 hour and 30 minutes.
.sp 1
The default is 2 hours.
.RE
.IP \fB-s\fR 14
Print a summary of messages that have been queued longer than
the specified or default time. Two separate types of summaries are printed.
The first summarizes the queue messages by destination host. The host name
is gleaned from the recipient addresses for each message.
Thus the actual host names for this summary should be taken with a grain
of salt since ruleset 0 has not been applied to the address the host was
taken from nor were MX records consulted. It would be possible to add
this; however, the execution time of the script would increase 
dramatically. The second summary is by status message.
.IP "\fB-u\fR \fIusers\fR"
Specify list of users to send a mail report to other than
the invoker. This option is only valid when \fB-m\fR has been
specified. Multiple recipients may be separated by spaces.
.IP "\fB-w\fR \fIwidth\fR"
Specify the page width to which the output should tailored. \fIwidth\fR
should be an integer representing some character position. The default is
80 or some other site configured value. Output is folded neatly to match 
\fIwidth\fR.

.ds mp \fBpostclip\fR
.SH NAME
\*(mp - send only the headers to Postmaster
.SH SYNOPSIS
\*(mp [ \fB-v\fR ] [ \fIto\fR ... ]
.SH DESCRIPTION
\*(mp  will forward non-delivery reports to a postmaster after deleting the body
of the message. This keeps bounced mail private and helps to avoid disk space problems. \*(mp tries its best to keep as much of the header trail as possible.
Hopefully only the original body of the message will be filtered. Only messages
that have a subject that begins with 'Returned mail:' are filtered. This
ensures that other mail is not accidently mucked with. Finally, note that
\fBsendmail\fR is used to deliver the message after it has been (possibly)
filtered. All of the original headers will remain intact.
.sp 1 
You can use this with any \fBsendmail\fR by modifying the Postmaster alias.
If you use IDA \fBsendmail\fR you could add the following to <machine>.m4:
.sp 1
.RS
define(POSTMASTERBOUNCE, mailer-errors)
.RE
.sp 1
In the aliases file, add a line similar to the following:
.sp 1
.RS
mailer-errors: "|/usr/local/bin/postclip postmaster"
.RE
.SH OPTIONS
.IP \fB-v\fR
Be verbose about delivery. Probably only useful when debugging \*(mp.
.IP \fIto\fR
A list of one or more e-mail ids to send the modified
Postmaster messages to. If none are specified postmaster
is used.
