Sendmail can't initiate an outgoing port 465 connection on its own. The
only way sendmail can use a secure outgoing connection is by starting out
unencrypted and using STARTTLS to switch to secure mode. Port 465 doesn't
work that way. I've been through that, consulted with the Gods, etc., and
the only way to make outgoing port 465 from sendmail work is to route the
connection via 'stunnel'. Yes, that can be done, but it's a bit of a
PITA, and I'm glad I don't have to do it any more.
Port 587 + STARTTLS should be quite straightforward, though I've never
had to play with the incoming side of that.
