Thanks John By the way I checked with my service provider. Their ISP does not block 25. But to successfully deliver SMTP mail, I need to use their relay server (it uses port 25 only).
Where will I configure their relay server . Is it in /etc/postfix/main.cfor any other file. Do I need to modify anyting in dovecot or amavisd configuration???
Thanks Austin

Some ISP's block port 25 if it is a 'home' type connection. Comcast recently started blocking and I can't connect there from home either.
configure your mail server to use your ISP's mail server as a 'smarthost', OR configure it to use an external (coloc or whatever) server as smarthost via port 587 with authentication.
