Are you ONLY running a caching server?

A good place to start to test DNS is:

dig website.yourdomain.com

Do you use the same domain internally?

Please post the output of above.  And it would not hurt to post the URL to your website.

Thanks for the reply, yes running cache server pointed local host in the /etc/resolv.conf and added forwarders entries.

executed the below commands
host shriramproperties.com
shriramproperties.com has address
shriramproperties.com mail is handled by 10 mail.shriramproperties.com.
indar@lampsrv:~$ dig www.shriramproperties.com
