[comp.mail.misc] Headers that sendmail can write

mrm@sceard.Sceard.COM (M.R.Murphy) (12/29/90)

Just to see if more bickering occurs :-)

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.

But why tack on the content free ".UUCP" pseudo-domain?  Why shouldn't
it simply say

	Received: from foo by nerf.herd.edu (5.61/1.292) with UUCP

I confess to being somewhat irked at the MEANINGLESS proliferation of
the UUCP pseudo-domain all over the place.  It was never more than a
bit of routing sleight-of-hand for Internet purposes, and shouldn't be
used where it doesn't apply.  (And DEFINITELY not where a site isn't
actually registered in the Zone.)
