I've experimented with direct-out-the-pipe delivery systems. Trust me, you don't want to go there. It's not trivial. Well, it's trivial for 90% of the world that follows the RFCs and behaves as expected and has the right DNS setups and isn't trying to outsmart spammers by being stupid. and you'll spend the other 90% of your time trying to build compatibility in with the other 10%.
Chuq, do you think it would be feasible for Mailman to try to handle that 90% itself, and then only hand-off to a Real MTA when it runs into trouble with the other 10% -- assuming it could know when it runs into trouble.
Also, there's incoming SMTP and outgoing SMTP. It may be possible to build in support for one direction without providing the other. (It also may not be worth it.)
