This behaviour seems common to all the uucp's I've come across from V7 to S5. For whatever reason if uucp (or more exactly uuxqt) has to reject a mail message rather than aim the rejection at the user who originated it it will be sent to whoever sent it from the immediate neighbour. Normally this will be uucp doing mail relaying. So failed mail aimed at x!y!z!user which gets stomped on at z will (if uuxqt has its evil way) be mailed to y!uucp Gosh! How usefull (I hear you cry)!!!! I was just thought I'd pass on this usefull info'. You can now all rush away and check your uucp mailboxes and work out what to do with any junked mail sent by far away sites aimed at even further away sites. Incidentally I patched this up in UKUUCP but for some reason it doesn't always work. If anyone has a *working* fix...... -- -------------- Lee McLoughlin <UK>!ukc!lmcl, west44!lee UKUUCP support.

This behavior has been fixed in several ways in many situations. Sites running advanced mailers (sendmail, etc.) usually are smart enough to route mail failure notifications back to the originator to the extent that he/she can be determined in a complex internet environment. A number of newer uucp's (including all of mine) use the new X. file "R" line (return address) convention to determine routing for failed mail, which helps quite a lot and allows multiple hop failed mail routing. --Lauren--
