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).

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!

Hi,
Thank you for your help with this question.
I am doing an install of Qmail Toaster on CentOS 5.6 using the
documentation located at
http://wiki.qmailtoaster.com/index.php/CentOS_5_QmailToaster_Install
This is a test run to learn so I can do this in a production
environment.
The docs say I need a DNS server. I am using my registrar's
DNS. Do I
still need Bind or djbdns?
Thank you for your help!

There are 2 roles which are involved with DNS, an Authoritative
server and a Recursor. An Authoritative server answers queries about
specific domains which it 'owns', while a Recursor, aka caching
nameserver, answers queries about any host in general. The two roles
are typically implemented on different hosts, which is generally
considered to be a good practice. While they can be implemented on a
single host, doing so is more complicated, and has inherent security
risks.
Your registrar's DNS will serve as the Authoritative DNS server for
your domain(s).
The inbound MTA portion of QMT (smtp) uses DNS quite a bit, so it's
a good idea to have a caching nameserver installed on the QMT host.
This minimizes network DNS traffic, although DNS packets (UDP)
really don't use much in the way of network resources to begin with.
I usually install the caching-nameserver package (or pdns-recursor),
add "nameserver 127.0.0.1" to the /etc/resolv.conf file, then forget
about it.
