I vaguely remember considering this before, and unfortunately you can't use
a Reader for incoming SMTP traffic as it will alter the data of 8-bit
message data (and possibly 7-bit). I'll give TLS with SMTP a whirl and see
if I can figure out the problem.

I would really like to add this support if possible, but if it does involve
significant changes, I agree we can postpone this.

Just 2 incoming more than likely. Outgoing messages (through
SmartTransport) don't really use any given port. I hadn't even thought
about adding TLS support to SmartTransport, although that does seem like a
good idea.
