Ahem....  As both came through my site I thought I'd explain.  The
From: line as it passes through here is unchanged.  If everyone did
that you'd get mail from user@decuac.UUCP and user@tove.ARPA on your
From: lines.

The From lines looked like the above.  While it *is* a bit ugly, and I
hope to see it "fixed," it *is* surely usable for reply.  Your mailer
should send to the first system on the path and so on down the line
until it finally gets to the system which gave you the "funny"
address.  We understand what to do with a domain.

Now if other sites broke the address after us I can't help that.  But
the "Path" you saw was a true path and quite usable.m And
host1!host2!host3!uset@host.dom is ambiguous as it is *normally*
handled differently on UUCP systems and ARPA systems.
