Don't worry about that; just set it to 25. That technically isn't the output port; MS
will pick that one automatically from a 1025->65535 range. The "output TCP port" they
are looking for is really the "remote TCP port", which is the one IMail is listening
on (25).
MS will listen on port 25, where other machines will connect to it using an ephemeral
port (one of the 1025->65535 range). Later, MS will send (on an ephemeral port) to
IMail (on port 25). Each TCP/IP connection uses an ephemeral port on the client side,
which connects to a known port (IE 25 for SMTP) on the server side. On the server
side, it actually gets switched around, but that's a story for another day.
