I'm not sure how this fails a reality test. Are any anti-spam measures
in place currently?  If not, mailman is certainly not the place to 
start. That place is the incoming mail MTA.  (If you run your own servers,
installing spamassassin shoundn't take too much time. If you're using a
hosting server, then they should already have spam filters in place. If
they don't/can't you might consider a service that does.)

Once the MTA filters out what it can, and tags the suspect spam as such,
-then- creating mailman filters does become an almost trivial task.

Please search the mailman user's list archives, there have been many
discussions about spam handling.
