What if I just wanted to by pass Bind for now and setup an MX record at my registrar? Would I just update my /etc/resolv.conf file with "nameserver IP-to-Registrar" the IP being the IP that the Domain resolves to?
I want to do this to prove everything is working then add Bind so I do not have too may things going at once. Thanks Again for your help!
