Thanks for the suggestion.  I am still somewhat noobish and those files
were new to me.  Thanks for teaching me.  :-)

Both files had only comments.  They were not the source of the problem.

However, I may have some progress to report.  I can now successfully
telnet to my system and (by hand) send mail to an account there.
Hooray!  I am not certain what fixed that.  I did reboot after sending
my email.  Maybe something got reset.

OTOH, external (outside of my LAN) mail servers are still not connecting
to my server to send mail to the email address I have been using for
testing.  I now am wondering if the problem is/was with DNS.  My local
configuration is okay, but I am embarrassed to say that I just
discovered that I had never entered an MX record where I have that
domain publically hosted.  (The previous incarnation of my mail server
was using a different domain.)  Now to wait for the new MX record to
propigate and see if that will do the trick!  A check of the maillog
shows that the server certainly is getting connections from spammers
attempting to send their trash to old domain.
