We seem to have a problem just recently recognized. We are using elm
and smail and have a direct connect to uunet. We have specified uunet
as our smarthost to uunet. Our domain name is s5000.sp.unisys.com.
Our route from the Internet is
....{various Internet relay sites}!alice!sx1100!s5000.
So now the problem: We send mail to a site via uunet (either by addressing
it directly or via the smarthost feature of smail). Smail tacks on our
domain address onto the mail. Now when the destination site does a reply,
it does NOT take the same path back to us that it took to him.
I.e, instead of the relatively short path via uunet, it takes the
longer Internet path as a result of his mailer using our domain address.
Is there a way to remedy this?
It seems that our problem is that sp.unisys.com is a domain address
residing in the Internet while s5000.sp.unisys.com is site residing
in the UUCP world. What to do?
In advance, thanks for your help!!

If uunet is supposed to forward internet mail for you, it should be listed in an MX record in your domain's nameserver. If you prefer that uunet is used rather than relay.cs.net, it should have a "preference" less than 10 (0 is highest preference).
