OOPS! Right you are, it would, if that is what I had actually had in the
zone. I should have looked at the zone rather than typing what my
(obviously faulty memory) thought I had done.
The athena.inc. zone contains (in part):
@ IN MX 5 sparta.athena.inc.
@ IN A 192.168.1.3 ; corinth.athena.inc.
www IN CNAME corinth
ntp IN CNAME minerva
corinth IN A 192.168.1.3
sparta IN A 192.168.1.8
win2000 IN A 192.168.1.13
minerva IN A 192.168.1.14

Let's try another MTA
$postfix hostmaster at www.usaid.gov. < /dev/null
Apr 03 09:18:38.700 client 192.168.1.14#35992: query: www.usaid.gov IN
MX
Apr 03 09:18:43.840 client 192.168.1.14#35993: query:
hera.info.usaid.gov IN MX
Apr 03 09:18:48.860 client 192.168.1.14#35994: query: www.usaid.gov IN A
Anyone else got MTA they can try? Make sure you use a mail domain that
is not in your cache.
Regard,
Jim
