Well, Seeing as its a quiet night on the list, I figured I'd share a 
procmail recipe that I use for the FNAL mailing lists.

This takes the email, matches the Sender header, then removes the 
[SCIENTIFIC-LINUX-USERS] from the subject, adds a List-Post: header so 
the "Reply to List" function works in Thunderbird, then files the email 
in its own IMAP mail folder!

## Scientific Linux Users mailing list.

* ^Sender: [log in to unmask]
| sed -e '/^Subject:/ s/\[SCIENTIFIC-LINUX-USERS\] *//g' && sed 
':a;N;$!ba;s/Precedence: list/Precedence: list\nList-Post: 
<mailto:[log in to unmask]>/g'
:0 A
.Mail\ Lists.SL-Users/

Now, as I know some mail clients will mess this up with wrapping lines, 
the following is the first two chars of a new line:

Procmail can do some pretty awesome email voodoo ;)
