I think your guess is probably right...at least, that's what I'm leaning
towards...when I trace the sending of an individual mail message, it fails
on what looks like a DNS query - (I'm on a steep learning curve here...
 8-) )   And our mail server was at one time our primary dns server - but is
no longer (this was before me - I've only been on board a few weeks) - yet
it almost looks like it's trying to query the mail server as a dns
server....

Here's a sample output - am I missing something obvious?  Any replaced
system names are fully qualified...

                Also, down at the bottom of the trace are these names....
prisoner.iana.org. hostmaster.root-servers.org .... what are these supposed
to be?  The second one doesn't even resolve...

                I've since removed the loopback address from the resolv.conf.

Lots of questions....please be patient?  Learning as fast as I can!  8-)

Guess:  DNS issues locally?
