It is querying my QDNS server running on another machine, with the provider
server as the backup. What is odd, is that when I assign 216.141.141.237 as
the mailserver's IP, EIMS will find its name (albeit the wrong name).
Changing to the actual IP x.253 and it does not. Very strange.

NO

Yes - I am aware of this, but the provider didn't want to complicate things
for the moment.
