You probably want to use procmail as a front to mailman. Modify your alias =
file and run the message through procmail first, and then pass it to =
mailman. I did a similar trick to block external e-mails to mailman to =
prevent non-employees being able to subscribe to our internal lists. =
Mailman cannot do this. Here is the method:

Modify /etc/aliases:

www-request:            "|/usr/bin/procmail -m LIST=3D'www' /etc/mail/procm=

This will call procmail instead of mailman. Mailman is called inside the =
procmail script:

:0                              # pass along all mail for eskom
* ^From:.*eskom.co.za
| /home/mailman/mail/wrapper mailcmd $LIST

:0                              # reply to all mail not from eskom
* !^X-Loop: owner-${LIST}@lists.eskom.co.za
   :0 hc
   | (formail -r -A"Precedence: bulk" \
                  -A"X-Loop: owner-${LIST}@lists.eskom.co.za" ; \
                 echo "\
This is an ESKOM internal mailing list to which you may not \
subscribe. If you have any queries, contact owner-${LIST}@lists.eskom.co.za=
for further information.") | \
                 $SENDMAIL -t -f owner-${LIST}@lists.eskom.co.za

:0                               # drop all other mail

Using this method and the procmailex manpage, you should be able to do =
what you want.
