Go for TMDA.  I've had it deployed here for near 8 months.  Most of my
lists receive ~40 SPAM messages per day, plus another ~20 virus messages
-- and that's in addition to basic list mail.  The -admin, and -owner
addresses receive almost as many.  Within those 8 months the number of
either that have made their way thru TMDA either to Mailman or me (as
-owner/-admin) can be counted on the fingers of two hands with fingers
left to spare.

Not bad for almost 8 months.

Even better the number of valid messages which their posters have not
bothered to confirm thru TMDA can be counted on the fingers of one hand.

TMDA __is__ your friend.
