Duncan--Thanks for your suggestions.  They were very easy to follow.
Unfortunately, I still get the same problem--and the interesting thing about
all this is that nothing hits the maillog.  Receiving logins hit the
maillog, but any smtp attempts outside the network don't show.  So--not sure
what to give you there.  When I telnet to the port from outside, the message
I get is:

telnet mail.myserver.com 25
trying [IP Address]
telnet:  connecto to address [IP Address]: Connection refused
telnet: Unable to connect to remote host

this looks like a firewall issue

However! I also tested inside outgoing and it is NOT working like I
thought. The message that comes up in the maillog on that one is

Mar 14 11:10:24 MYSERVER postfix/smtp[4391]: C80AE1C0D0:
to=<coreyhead yahoo com>, relay=none, delay=189, status=deferred (connect to
MYSERVER.com [IP Address]: Connection timed out

and this too...
