chuqui@nsc.UUCP (Chuq Von Rospach) (10/16/85)
Sigh.... I've caught this message passing between my system and ihnp4 about
3 times now, so I finally intercepted it. As near as I can figure out,
someone over in the UK tried to send something through nsc!voder, mispelled
the site name as 'vodor' and it died here at nsc. Our mailer daemon tried
to rebuild a return address, shipped it back to ihnp4, which barfed on the
return address, and tried to send it back again. I've seen it bounce three
times today, between our mailer daemon and ihnp4. I suggest that anyone
trying to build routing systems think VERY hard about how they are doing it
-- it is obvious that many systems out there generate addresses that break
other mailers... what I'm wondering now is how long it would have bounced
between my mailer and ihnp4 before the system threw it away -- anyone for
infinite mailing loops?

One useful convention is that if a message is from mailer-daemon, and you get an error in trying to route it, just drop it on the floor. Don't try to generate another error. I would check the from field for mailer-daemon or MAILER-DAEMON anywhere in the address.
