Thought I would add some additional information here, in hopes of 
helping find out what the problem is.

Here are the contents of the /etc/resolv.conf file, on the server that 
has sendmail and BIND 9 running:

domain  mydomain.com
nameserver  192.168.1.165

Granted, im young to DNS and BIND here, but starting to realize a few 
things. What im curious about is, since our ISP controls our domain and 
it's nameservers are authoratitve for our domain, my thoughts are that, 
i've buggered something up here.

I feel like it's right on the tip of my tongue, but can't place it. I 
thought i'd post part of my named.conf, in hopes of finding the problem:

options {
         directory "/etc/namedb";

         forwarders {
                 216.xxx.xxx.xxx;
                 216.xxx.xxx.xxx;
         };
};

zone "." {
         type hint;
         file "named.root";
};

zone "0.0.127.IN-ADDR.ARPA" {
         type master;
         file "localhost.rev";


It was recommended to me that I use the forwarders of our ISP to take 
advantage of their DNS servers. Could this be a problem?

I'm close, very close I feel but just can't figure it out.

I appreciate the help.

Cheers,

Jason
