Actually I figured it out... Postfix is looking up its own hostname
against DNS.  If it finds a CNAME record (which it did), it traces back
to the A record (which was not publicly resolvable).  So the answer was
to use an A record in DNS and not a CNAME.

I've also been trying RAV antivirus with Postfix and so far it is
working very nicely, FWIW.
