	Sendmail has milter, and that has now been brought into postfix 
(as of 2.3), but I can't speak for any other MTAs.  What would need 
to happen would be a custom program would have to be written for each 
MTA to interact with it in the way that MTA works, but which has a 
deep understanding of Mailman and the configuration for each list and 
recipient, and could effectively do a "dry run" for each message.

	Of course, this would have to happen after the 
anti-spam/anti-virus milters, and then some sites are going to use 
accept & scan techniques as opposed to milter, so there may need to 
be multiple different "MTA adapters", even for a particular MTA.
