In the new mailman (whcih we also use) there should be header filtering.
It should be possible to filter based on Content-type: however that
doesnt help with content-length.

The new one can auto discard spam, andyou can even do it sans notification.
(I do it with, so I get the spam, but just to see what's being discarded
in case some lost sheep subscriber is posting incorrectly to my relatively
private lists.)

Its not bad. Now if I could only figure out why it uses a cluster worth
of CPU to deliver messages, I'd be happy with mailman. :) (1.2Ghz CPU
doing about 20-30% cpu 24hrs a day to send 2000 posts-recipient :( )
