-> offer SMTP on port 587, SMTP-AUTH only

How many mail clients actually support that?  Most I've seen want a
regular SMTP server to talk to.

Yes, a lot of mail clients would need to be fixed. Do clients
correctly implement things like SMTP-AUTH or STARTTLS nowadays? How
many are still 
relying on SMTP after POP?

Evolution can do SMTP-AUTH or POP before SMTP, and on any ports you care
to specify.  MS Outlook also supports SMTP-AUTH and will let you define
ports.  I used to use TheBat! Also, and if I recall correctly, it
allowed you to specify arbitrary ports as well.  I think there are
probably fewer clients that would need to be fixed than you may think.

FYI...
