>Subscription options for Carol Winship <[log in to unmask]>, list AUTOCAT: >Ack=Yes, Mail=Yes, Files=No, Repro=Yes, Header=Short, Conceal=No Dear Carol (or Douglas ;-)): I think you should possibly investigate the DNSes that control the name/IP and IP/name lookup for TENET.EDU. There is some evidence that things are a little screwed up: One probe (using DiG) revealed that TENET.EDU has an A record of tenet.edu. 66858 IN A 198.213.2.7 and a MX record of tenet.edu. 86028 IN MX 100 Paula-Formby.tenet.edu. which has an A record of paula-formby.tenet.edu. 72725 IN A 198.213.2.2 Doing a reverse lookup of ..2.7 7.2.213.198.in-addr.arpa. 85821 IN PTR Kay-Abernathy.tenet.edu. Looking up Kay-Abernathy "A" record kay-abernathy.tenet.edu. 85722 IN A 198.213.2.7 Doing a reverse lookup of ..2.2 2.2.213.198.in-addr.arpa. 25143 IN PTR Paula-Formby.tenet.edu. I did not check all of the authoritative NS for tenet.edu to see if they were consistent. Also, I would check the kay-abernathy machine to see if that has an SMTP Server started or undelivered e-mail (possibly some SMTP clients don't handle MX?).
