Sanjay posted his approach, which is probably the best you can do for now without hacking the code. An idea we threw around last year was to have configurable filters the message could pass through. One such filter could either strip or reject attachments, similar to what you describe.

Another option for the time being involves wrapping your aliases with a filter like procmail. This is what I do for my majordomo lists or any place that I need extra filtering (note the majordomo slant of these recipes, but I've converted stuff enough here so that it should apply to Mailman...) And yes, it's a hack. :)

listname :"|/usr/bin/procmail -m LIST='listname' EXTRA='' /etc/mail/procmailrc.lists" listname-admin :"|/home/staff/mailman/mail/wrapper mailowner listname" listname-request :"|/home/staff/mailman/mail/wrapper mailcmd listname" owner-listname :listname-admin listname-owner :listname-admin

/etc/mail/procmailrc.lists looks like this:

PATH=/usr/bin:/usr/local/bin:/bin HOME=/etc/mail

# if EXTRA isn't set to an archiver or something, set to devnull # so that we have another address to hide the -outgoing address # in the Received: headers -- another ugly majordomo-required # hack :0

• EXTRA ?? ^^^^ { EXTRA="devnull" }

check against message-id database to make sure that this isn't

# a duplicate post :0 Wh: $HOME/list-cache/${LIST}.lock | formail -D 8192 $HOME/list-cache/${LIST}.cache

# mail people to let them know that I don't like attachments # on the list :0

• ^(Content-Type: multipart/mixed;|X-MS-Attachment: WINMAIL.DAT)
• ! ^FROM_DAEMON
• ! $ ^X-Listname: ${LIST}@mallorn.com { :0 hc | (formail -r -A"Precedence: bulk"
  -A"X-Listname: ${LIST}@mallorn.com"
  -A"From: owner-${LIST}@mallorn.com" ;
  cat "/usr/lib/mail/reply.mime" | sed s/LISTNAME/${LIST}/) | $SENDMAIL -t -f owner-${LIST}@mallorn.com }

:0 | /home/staff/mailman/mail/wrapper post $LIST,$EXTRA
