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.  :)
