Uh-huh. Right. Look at the headers here before you. Try to tell me
where it came from, or where it was going, or how it tried to get
there. I have no idea...
("%ification wraps" have their place, but this is definitely not it.)
Notice that this thing has been bouncing around the countryside for
more than a week. The first Received: line at the very bottom says 10
Mar 88.
It appears that our NNTP link with mailrus.cc.umich.edu figures
prominently in why it ended up here. UMich gave up and somehow
concluded that it came from here, which wasn't true; but when
mailer-daemons start talking to each other, anything can happen.

Host unknown > > ----- Unsent message follows ----- My bet is that someone was mailing along the news path, a longish one that it looked like mcf!mibte!fmsrl7!eecae.ee.msu.edu!(unknown)!mailrus.cc.umich.edu! tut.cis.ohio-state.edu!bloom-beacon!mit-eddie!bbn!rochester!(something about CMU). The sad part is that the path could have gone mcf!umix!host.cs.cmu.edu!person and avoided all this troubles. I don't know if the problem is at mailrus (might be, gotta check) or with one of the CMU machines not forwarding stuff along beyond their local domain, or confusion resulting from the eecae.ee name, or whatever. With a path as pathological as the one presented, it's a wonder that anything happened to it at all. --Ed

I would suspect that the problem is at the sending end, and that the sendmail is not configured to use MX records. If the sending host is configured to use MX's, then it might be a problem that the target host of the MX is not yet ready, but that is just a guess.

Both domains have primary and secondary forwarders >- so it seems strange that this is happening... the problem in our case (for the domain rn.com) is that our primary forwarder was specifing *.rn.com -> nstar - which didn't forward everything like it should (he is using sendmail). if he put nstar.rn.com -> nstar everything works just fine - so the problem is related to the *.rn.com in the cf file. like I mentioned in a previous article - everything was working just dandy until about 10 days ago (with the *.rn.com) strange indeed.. -- Larry Snyder, Northern Star Communications, Notre Dame, IN USA {larry@nstar.rn.com, uunet!nstar!larry, larry%nstar@iuvax.cs.indiana.edu} backbone usenet newsfeeds available Public Access Unix Site (219) 289-0282 (5 high speed lines)
