In article <01RK5KUREEZA000058(_at_)mauve(_dot_)mrochek(_dot_)com> you write:
should we think about technical means to facilitate the latter?
Absolutely not. Relaying mail is complicated enough already; adding another
port and DNS lookup to the mix and all the associated failure modes consistutes
a huge cost with no real benefit.
Agreed, the extra overhead of HELO and STARTTLS is not important, and the net is
already overoptimized for mail on port 25.
I am reasonably sure that if we didn't already have port 465 in
addition to 587, nobody would invent it.
