Err, its last year's trade-off.  Not necessary any more.

Front the list with TMDA with your inbound filter pointed at the list
subscriber base.  Posts from subscribed members go straight thru.  Posts
from non-members get held until they (the poster) confirms that they
really did (mean to) send the mail.

It works quite nicely.

Mailman v2.1 can set auto-discard for such posts.  That's a partial
solution and kills useful posts from non-subscribers and subscribers
posting from different addresses.  Fronting with TMDA allows you to
still let non-subscribed posts thru if the poster gives a little extra
push (no attention required from you).  Damned sweet really.
