A Simple Procmail Listserver

This is recipe that will turn procmail into a
simple mailing list server.

:0
* ^Subject.*\[LIST\]
* ^From:.*\/[A-Za-z0-9_.+-]+@[A-Za-z0-9_.+-]+\.[A-Za-z0-9]+
* ? grep -i "$MATCH" ${HOME}/list2
{

:0c
| `echo $MATCH > $HOME/match`

:0c
| `${HOME}/append.sh`

:0f
| sed -f ${HOME}/append.sed

LIST=`cat ${HOME}/list`

:0c
LIST

:0f
| formail -I"From: LIST " \
-I"Reply-To: your@email.address"

:0
! ${LIST}

}

\[LIST\] put whatever string you want in there to identify the
list to its subscribers and to procmail.

${HOME}/list2 contains the email addresses followed by a space,
followed by that subscriber's handle. One pair per line. This
handle is appended to the bottom of any posts they make.

Their email address will not appear in mail from the list.

${HOME}/list contains just their email addresses, one per line.


(Below, the dashed lines "----------..." are there to indicate
the boundaries of the files, not to be included in them.)

${HOME}/append.sh:

----------------
#!/bin/bash

var=`cat ${HOME}/match`

var2=`sed -n "/$var/s/^\($var *\)\(.*\)/\2/p" ${HOME}/list2`

sed "\$s/.*/${var2}/" ${HOME}/append.sed > \
${HOME}/tempsedxx11Yp341

mv ${HOME}/tempsedxx11Yp341 ${HOME}/append.sed
-----------------


${HOME}/append.sed:

------------------
$a\
This post is from:\
xxxxxx
------------------

If a mail arrives that has the string [LIST] on the subject
line, and it is from someone who is subscribed to the list,
a copy of that mail, with their handle at the bottom, will
be sent to everyone on the list and a copy will be saved
to your mailbox LIST.

I've changed this so that the subscriber's handle shows up on
the From line of posts from the list.

This will allow subscribers to killfile posts from subscribers
they don't want to hear from with ease.

Switch this for the above:

:0f
| formail -I"From: `cat $HOME/match` <${LIST}@.whatever.com> \
-I"Reply-To: your@email.address"

Add this line to the end.

echo "$var2" > ${HOME}/match

And who in hell, exactly, asked you?

Nobody cares, Beavis. You're a kook. An a barely literate kook. You have
to be insane to run any code you vomit forth. Doing would put you in danger
of getting compromised by someone smarter than you, who knows how to exploit
bugs in your code.
