Gee, with all those mixed-mode addresses I have no idea where *anybody* is.

The only one I know of for sure is "emory!whm@arizona.edu".  The only
way that could have come about is if emory prepended its' hostname to
the address.  (I happen to know that Bill Mitchell is at arizona,
which is backed up by the Message-ID: and first Received: headers).

As has been gone over countless times, the meaning of that address
depends on how we interpret that address.  If we give preference to
the ! then it happens to work.  If we give preference to the @ then
it doesn't work.  Since we are a {CSNET,INTERNET}/{BITNET,UUCP} site
(with that order of paying-attention-to-standards) we give preference
to the @, meaning that any of the mail we receive from the mtxinu
mailing list will be un-replyable.
