The other posters aren't talking about port forwarding, they're talking about the (deprecated but still in use) SSL-on-connect usage of port 465 and the use of port 587 as an MSA (Message Submission Agent) port. Port 25 is historically used for everything - MTA (Message Transfer Agent) and MSA together, but there's momentum now behind getting users to use port 587 and authentication in many quarters. It makes applying local policies to submitted (as opposed to relayed from other MTAs) messages rather more easy. > accept > hosts = +relay_from_hosts > control = submission/sender_retain > > accept > authenticated = * > control = submission/sender_retain > > but my relay_from_hosts list is empty.

That way madness lies - other users, who aren't yours, using the same ISP will be able to relay arbitrarily. Make your users use port 587 for outgoing email, and make them authenticate. That way you can allow them to do so from anywhere in the world and you have an easy recipe for tracking any abuse.
