Just set up your authoritative DNS (A,MX) records at your registrar. QMT doesn't need to know about that at all. Then on QMT, simply: # yum install caching-nameserver # service start named # chkconfig named on Then put nameserver 127.0.0.1 as the first record in your /etc/resolv.conf file. That's all you need to do. Your QMT host doesn't give a hoot about authoritative DNS. It'll get everything it needs from the recursor (aka caching-nameserver). -- -Eric 'shubes' On 04/26/2011 12:24 PM, Keith Smith wrote: > What if I just wanted to by pass Bind for now and setup an MX record at > my registrar?

I had to do this on the new machine I just recently built as well.
