Sorry... I had looked around on the archives quite a bit and hadn't found
anything useful.  Although I didn't now exactly which search terms would
help either.  But regardless...

That would be the optimal solution, except that if I set up the DNS to
resolve to an internal IP address, then no outside machines would be able
to contact the mail server.  Which brings up another question:  Is there a
way I could set up my DNS server to resolve a given hostname to one IP for
requests coming from certain IP addresses, and to another IP for all the
other IPs?

TIA
