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?).
