kindely reply meeee............

Firstly, PLEASE use code tags, notice the difference in readability between your post and mine? That is why... 'nuff said.

This is the result you are looking for. The ANSWER section, which is missing from your "localhost" results.
This is will use the nameserver set in /etc/resolv.conf

To test if the dns will resolve on localhost, you need to specify it when using dig. ie:
No, the result is missing the ANSWER section.

I would suggest checking /var/log/messages, for errors when you start named, and also starting named from the commandline.

I would also suggest you learn about the following tools, they can be greatly beneficial in diagnosing problems with configs, and zones.
-> named-bootconf
-> named-checkconf
-> named-checkzone

I am not an expert on BIND, i tend to take my working zone file, and modify it to suit a new situation. But a significant difference that i notice between my config and yours, is that i have an additional A record between my NS and MX records. But, there is every probability that my config is wrong, but works anyway.
This is the relevant part of my zone file..

i dont understand what u tring to say

What don't you understand?

what salution u sugest

What don't you understand about that...

check your MX entry and remove the ;

also change the serial key when you make any changes to your DNS zone file and restart the service

try this and post the output
If this also does not works post your file using code tags
