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.
