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.
