We recently installed a Raptor Eagle NT firewall, and as such is mangles
dns functioning in that it seems impossible to find out what is really
supposed to be pointing to what. Real named was so much easier...

Our MX machine is inside the firewall of course but are the MX records
supposed to point to the real MX machine or the firewall ?

ferc2 is the f/w but ferc3 is our inside mx machine.
