Unfortunately, I have tried the suggestion quoted below to no avail. Regardless of the fact that the submission port already exists as a service, and all instances of the submission line have been uncommented in the /etc/postfix/master.cf file, the server refuses to respond to port 587. The router I have in front of the server, acting as firewall, logs the fact that the attempt has been forwarded, but telnet gets “connection refused” and, of course, mail clients cannot specify port 587.
All this because some networks refuse to allow outgoing port 25. Freakin’ free wireless networks…
I have VPN in place as an alternative, but it would be extremely nice to have this work.
Thanks for any help available.

Open up /etc/postfix/master.cf
Uncomment the following line:
submission inet n – n – – smtpd
Open up the submission port (587) on your firewall and if necessary, set up port forwarding to the mail server on 587.
Just do a quick telnet on port 587 to check if it is working fine.[/QUOTE]
Port 587 is the standard alternate port. I would recommend 50025 if you are looking for a port that is easy to remember and not likely to be used. Many port scanners will also go through port 1-10000 and then move on.
