    But an address must have soething to the right of the "@" and must
    contain the "@" as well!

Once a messagessed to foo@bar is received by bar it may convert the
address into any internal form it pleases, which generally begins by
removing the "@bar".  After UCLA-LOCUS forwards the message to UCB-VAX
it is no longer in an SMTP environment, so @'s are no longer needed.

Perhaps the wording of the steps was misleading, and I was inferring
something different from you.  It says that the header in step 3 was the
way the message was received by UCB-VAX.  I interpreted that to mean
that this was what the header looked like after UCB-VAX received and
munged it.

Anyway, we are arguing minor semantics.  The point of the message is
obvious:  UUCP hosts are all expected to know a route to an Arpa
gateway, so the explicit route (with !'s) only has to be specified for
the part of the route after traversing the Arpanet.  As I said in a
previous message, this is not realistic.  What is to stop hosta from
thinking hostb is closer to the Arpanet and vice-versa, causing all Arpa
mail from or thru either host to loop forever?
