Our e-mail server has a private address of 10.x.x.x with a static map in the NAT pool on our router. Our ISP maintains our DNS records. When using nslookup internally (on the 10.x.x.x network) it returns the private address of our e-mail server. When nslookup is run externally, the NAT (public) address is returned.
My question is what governs the address returned by the nslookup query?
