[Mailer@IU.AI.SRI.COM: Undeliverable message]
I maintain a mailing list with a couple of addresses that go to
BCO-MULTICS. I have for some time been getting back lots of failures of
the following type. In checking this out, I found that the NIC reports
three servers (ALTURA.HONEYWELL.COM, PULSAR.HONEYWELL.COM, and
EUROPA.HONEYWELL.COM). In querying the three servers just now, I found
that ALTURA gave a correct response when queried for the address of
BCO-MULTICS.HBI.HONEYWELL.COM, PULSAR gave a Non-Existent Domain reply,
and EUROPA didn't respond. When I checked again a little later, PULSAR gave
the correct response for BCO-MULTICS.HBI.HONEYWELL.COM.
Our mail system depends upon the domain system to provide correct responses.
If a server for HONEYWELL.COM reports that BCO-MULTICS.HBI.HONEYWELL.COM
is an non-existent domain, then the mail gets returned.
I have seen this type of error (where incorrect answers were given sometimes)
before in domain servers at MIT. If your domain servers may be the
same as theirs, then I can point you to the people there that tracked
down what was going on.
This problem has apparently been occuring for a long time (weeks or months).
