It is possible to set up moderation.  Actually, moderation is a wrong 
word.  The only responsibility of the moderator show be preventing spam.
  
It is also possible to improve filtering without restricting posts to the
subscribers.  In particular, HTML should be banned because of it's 
potential for abuse.  Also there are many headers specific to spam, e.g. 
"X-Mailer: Caretop" or empty "Date:"

There are two things mailman cannot do (as far as I know, without patching
it):

1) It cannot check the body of the message.
2) It cannot discard spam without moderator's approval.
3) It cannot combine conditions.

That's what I'm using in my lists:

Subject:[ (]*no subject[) ]*$
Subject: *$
Subject: *[A-Za-z]scribe$
Subject:.*                     .*
Subject:.*(product|sex|stock|revenue|sale|rich|toner|manegment|adv)
Subject: *(antigen|scanmail)
Content-Type: *text/html
From: Hahaha <address@hidden>
