Is sounds as though there is something amiss in your djbdns configuration.
If you really want to use djbdns for some reason, I've found "The Linux
Cookbook" by Carla Schroeder to be a good reference for that. I don't
presently have my copy nearby.
I've found that it's much easier to use the caching-nameserver package
if you're using CentOS. Simply remove the djbdns package, then install
caching-nameserver:
# rpm -e djbdns
# yum install caching-nameserver
I expect that will fix things up for you.

Hi,
I tried the following on the mail server itself and i got the reply
immediately.
[r...@mail init.d]# nslookup 122.175.72.62
Server: 127.0.0.1
Address: 127.0.0.1#53

It seems that i have djbdns install rather than BIND for my
qmailtoaster. Can i check how can i configure the forwarders on my
caching server? The mail server setup is by default according to the
Qmailtoaster installation guide.
Thanks

Hi YongSan,
I tested to connect to your server on port 25.
It takes about 2-3 min to get the greeting-banner ("220
localhost.localdomainhe
- Welcome to Qmail Toaster Ver. 1.3 SMTP Server ESMTP")
For me that looks like your server takes ages to resolve my senders
reverse
dns.
Did you configure the forwarders on your caching dns server on
localhost?
How long does it take to resolve f.ex. 122.175.72.62 ?
Some times ago I had the same behaviour on a clients qmail-box where the
config. of bind disallowed querys from localhost (127.0.0.1).
