To check the status of the local caching nameserver:
# service named status
If you have an interface on your QMT that uses dhcp, that can overwrite
your resolv.conf file. Your interface(s) on your QMT should be defined
as static.
Once you have your caching nameserver installed, your resolv.conf file
should contain "nameserver 127.0.0.1" as the first entry. As a backup,
in the event that your caching nameserver has a problem, you might want
to add "nameserver 208.67.222.220" and/or "nameserver 208.67.222.222"
(opendns.org resolvers). Or you could use your internet provider's
resolver(s) if you'd like. They'd likely be a tiny bit faster (because
they're closer).
You can use the 'dig' command to test your local resolver, as well as
other resolvers. 'man dig' for options.

Today after configuring local DNS I think my caching DNS was break. It
doesn't had entry "nameserver 127.0.0.1". So reinstalling
caching-nameserver.
Lets see if it solves the problem.
Thanks Eric and Martin. Will update you back by tomorrow.

Of course the caching-nameserver is the best way, but under certain
circumstances I have used the host file successfully for testing. This
however was for web not mail services.
