Some uucp mail sites are trying to get smarter about how to route
things, and wind up messing things up.  Apperently they realize that
oberon.usc.edu (citvax!oberon) is willing to gateway mail to the
.usc.edu domain, so they create a uucp path to forward the mail to
oberon.  However, many (most?) of the intermediate sites are also on
the arpanet, and take @ at higher presidence than ! when routing
mail.  The mail gets to my site, but the address is not correct
(contians multiple !) and gets rejected.  The rejection message then
gets rejected because it was converted to upper case (my mailer does
this to host names and local addresses) and uucp is case sensitive.
The mail does get to the correct place, since the rejected rejection
is delivered to a human (me).  (I'm postmaster and info-prime-request
as well as r.larson)

Is there any solution to this problem?  (Fixing my mailer not to
uppercase the rejection just throws it at someon else.)

Here is an example header:  (The @ and % are reversed in the original
To: address, but I've got others without that problem.)
cup.portal.com is not the only site guilty of this.
