The underline and bold sentense is my problem.

That highlighted text tells you exactly what the error is, it can't find an MX record for the domain you're sending to. You'll have to do some checks from your own server to see if there is an MX host record for that domain.

Dear Bill,

Will u please tell me how to create MX record for yahoo.com on my server.

You don't create an MX record for any domain other than your own, you have to check if one exists by using the DNS tools available to you in your linux distribution.

Dear all,
My problem is solved by myself only. First I have changed the sequence in resolve.conf file. The sequence of DNS provided by my ISP is given first preference and the local DNS has given second preference and one firewall rule is added to accept the outgoing traffic from my STATIC IP to the local port 7025. Its resolving all the domains. The result of nslookup yahoo.com is as below -

[root@pudhari ~]# nslookup yahoo.com
Server: 218.248.241.2
Address: 218.248.241.2#53
