Thor, 587 running SMTP auth (and relaying for authenticated users) and port 25 for local (non relay) delivery without authentication should be the default on all servers.
Agreed! At the very least you get the benefit of an electronic trail to follow if one of your users *is* spamming.. :) If you only relay mail from authenticated users, drop (not bounce) any mail destined for a non-existant account, and use reasonable spam blocking and tagging, you should be able to reduce spam to a slow trickle.. It's working here, thus far... And I don't have authentication fully implemented yet. :)
