That doesn't change the fact that plenty of MUAs do not properly
handle alternative ports.

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.
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.
