Procmail

George_Warnagiris · February 5, 2002, 2:55am

I have a problem using procmail with RT and I though you may be able to
help. I have been assigned the task of cleaning up after my department’s
Exchange administrators. All SMTP email that leaves the Exchange servers
have a disclaimer appended. For obvious reasons, I am trying to filter this
disclaimer before it hits RT. I have created a procmail recipe that uses
perl to strip the unwanted text. I though this should be invoked in the
aliases file like this:

helpdeskus: “| procmail /etc/.procmailrc | /opt/rt2/bin/rt-mailgate --queue
helpdeskus --action correspond”

It, unfortunately, sends a blank, header-less, body-less email to RT. I’m
not sure what I’m doing wrong here. I thought you may be able to suggest a
better place to invoke procmail. Maybe I should insert perl directly into
RT to perform this?

Any thoughts or suggestions on this mater would be appreciated.

Thanks,
George

Hi, sorry if this has been asked before? I didn’t find it on a quick trip
through the archives though.

Is there a way to select only certain tickets from a queue by keywords,
using the command line interface? I haven’t used RT since the v.1 days,
and I’ve so far found the keywords under the web interface to be a great
thing. I really rely on the command line interface though, as I base
shell scripts off of the CLI tools.

I was doing stuff like:

rt --limit-queue=general --summary %id5%subject80%owner10%due20%status8

I can’t find a keyword object in the documentation.

Any help or ideas? Hopefully it’s a simple thing that I haven’t figured
out in the new version yet

Thanks,

Wes

You would be better off invoking rt-mailgate from within the procmailrc.
I do my mail delivery to RT via:

aliases file:
# Run rt2 as the rt2 user, not as root.
test-rt2: “| /usr/bin/procmail -m /etc/procmailrcs/rt2-test”

/etc/procmailrcs/rt2-test:

# This file MUST be owned by the rt2 user.  See '-m' description
# in the procmail man page.
HOME=/home/rt2
INCLUDERC=$HOME/.procmailrc-test

# are we still here after including?  Dump it to someone
:0
! joe_bloggs@example.com

( The above two snippets gets procmail running, as the rt2 user, a
procmail file for the specific queue. I really really dislike relying
on setuid stuff. )

/home/rt2/.procmailrc-test

# This file does any filtering/mail manipulations/etc before
# calling rt-mailgate.

HOME=/home/rt2
LOGFILE=log/procmail.log
VERBOSE=no

# Go away you naughty annoying spammer
:0
* ^From:.*badguy@example.com
/dev/null

# Place mailfiltering here

| /home/rt2/bin/my_custom_filter_program

# Accept the mail into mailgate.  We { } enclose it incase we want
# a last-ditch filter.
:0
{
  # Use a lockfile to ensure only one rt-mailgate process.
  :0 :.procmail.lock
  | /home/rt2/bin/rt-mailgate --queue TEST --action correspond

  # Something went wrong.  Dump it to someone

}

Bruce,

I just wanted to let you know that your advice has been very instrumental in
helping to get this going. I have successfully implemented and tested the
disclaimer filter. I really appreciate the time you have spent on this
issue. I owe you a beer next time you’re in NYC.

For the list, here is my final /etc/aliases entry, procmail recipe and perl
script. I hope this helps.

George

RELEVANT /etc/aliases FILE:

#RT STuff

helpdeskus: “| /usr/bin/procmail -m /etc/procmailrcs/disclaim-filter”
#helpdeskus: “| /opt/rt2/bin/rt-mailgate --queue helpdeskus --action
correspond”

MAIN PROCMAIL RECIPE> mmain

:>

#This file must be owned by the rt user
HOME=/home/rt
INCLUDERC=$HOME/.procmailrc
LOGFILE=/tmp/disclaimstrip.log
VERBOSE=on
SHELL = /bin/bash

0
! me@domain

So now procmail is acting as the user “rt”. Here’s were it all
happens, the > INCLUDERC file /home/rt/.procmailrc:

This file does any filtering/mail manipulations/etc before # calling

rt-mailgate.
HOME=/home/rt
LOGFILE=log/procmail.log
VERBOSE=yes

Place mailfiltering here

:0 wfb
|/usr/local/scripts/strip.disclaim

0
{

Use a lockfile to ensure only one rt-mailgate process.
    :0:.procmail.lock
    |/opt/rt2/bin/rt-mailgate --queue helpdeskus --action correspond
Something went wrong. Dump it to someone
    :0e
    ! me@domain
}

And finally, here is the real simple perl script:

#!/usr/bin/perl -w

undef $/; #We want to treat STDIN as one line

$input = <>;

$input =~ s/This email message may contain information(.*?)free of
errors or
viruses.//smg;

$/ = “\n”;

print $input;
