I'm sorry, I don't have enough information to answer your question. We don't
maintain our own DNS and it has been several years since I have had to work
with those types of issues. I think things are complicated by the fact of
having internal and external IPs, etc.
I have done a little more research on our end. The machine is named
newmail.esc8.net. It has an IP address of 10.44.127.7 (obviously an internal
IP). In the IMail administrator, there are two IP addresses configured,
10.44.127.7 AND 10.44.0.7. Both are named 'newmail.esc8.net' with the
aliases of 'mail.esc8.net' and 'esc8.net'. All of the other mail domains are
configured as virtual hosts, e.g., nb.esc8.net is $virtual007.
When I go to name-space.com and do a nslookup for 'newmail.esc8.net', it
comes back to 'mail.esc8.net' with an IP of 208.48.19.32 and an alias of
'newmail.esc8.net'. If I do a nslookup on 'nb.esc8.net', I get the same
results except 'nb.esc8.net' is listed as the alias.
However, whenever I do a reverse lookup for any of the other mail domains,
e.g., mvisd.esc8.net, I get this message 'Reverse lookup produced no
results. The IP number MVISD.ESC8.NET does not appear to be inverse-mapped
to a domain name.'
Now, what's really interesting is when I do a nslookup for 208.48.19.32, I
get the same error message as above, 'Reverse lookup produced no results...'
I'm not sure what all that means but that's some additional information I
didn't have before.

another thought, are you sure your DNS reverse zone is perfect, esp for you
mail server ip addresses?
