So really, it's looking like I need to create DNS records for all of the
internal machines also then? For internal use only?

I'm thinking this because on the compdev machine, I tried nslookup for itself
and it fails. Am I overlooking a simpler way of doing this? I just need
internal machines to be able to send email out using the QMT machines.

Mike
