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!!
