In practice if your remote users don't use the submit port on your servers
it gives rise to all kinds of different issues involving you trying to
support the outbound filtering AOL is doing on your customers sending from
non AOL domains.
Unfortunately, plenty of MUAs, even ones old enough to have been
around when POP-before-SMTP was the only authentication measure
around, still don't support this, or don't support it correctly.
Or you support POP AUTH, which just works, is in widespread use (probably
the most widespread of the methods of authenticating the submit port after
allowing relaying by IP), and was implemented years ago when open relays
Hell, damn few clients do plain-jane POP or SMTP anywhere
remotely close to correctly. Expecting them to do anything more
advanced than that will be an exercise in frustration.
You can't just set a hard and fast rule (like "let them eat
cake"), and automatically expect all MUAs to kow-tow overnight.
