I'm not sure why it works but it does work.  I suspect it's like this:
nt01.wejit.com is
the primary mailhost but ns1.wejit.com is the secondary;  so when the sender
can't find nt01 it goes to ns1.  Then, ns1 (who is permitted to relay) finds
nt01's address either in it's /etc/hosts or from our internal DNS server and
sends it on.

The owner?  I don't understand - how would I find that?  I grepped the file for
nt01, you can see the results above.
