Thanks for the reply..

I have followed the Document and changed  accordingly. After the server restart I have faced the host 0r domain not found error. Then I changed the  domain name in /var/spool/postfix/etc/resolv.conf.


Now I'm facing another issue.


After the host name change All mails are waiting in queue long time

Pls help me to resolve the problem.....

Thanks In Advance
