   How's about the writing of headers like
       Received: from foo.UUCP by nerf.herd.edu (5.61/1.292) with UUCP
   when foo was really foo.bar.com. And said so. And the transport was UUCP.
   Why doesn't it say
       Received: from foo.bar.com by nerf.herd.edu (5.61/1.292) with UUCP
   Does anybody get this right? What is right?

At the level of UUCP transport, a machine identifies itself with a
one-word hostname.  That is, UUCP host "foo" did not in fact identify
itself _during_rmail_execution_ as "foo.bar.com," but rather as just
plain old "foo."  (E.g., if you use smail 2.5 as your UUCP router
under sendmail, hence rmail is actually smail in disguise, smail will
generate a sendmail invocation something like
	/usr/lib/sendmail -em -ffoo!user 'someone@destina.tion'
for you.)  At that level, a Received: showing "foo.UUCP" is right.
But the references to foo.bar.com should be preserved within From:,
To:, and so on.
