We do this very simply. We use submission (587) with ssl and
authentication for road warriors. we don't greylist 587, and we don't
take unauthenticated un-ssl'ed connections on it. We tell people *not*
to use port 25 for this sort of thing. Spammers don't authenticate on
port 587 so there is no spam danger.
