Postfix Dovecot Mail Server not receiving mails from hotmail gmail, etc - open to bidding

Open

I configured a Postfix server on Ubuntu [url removed, login to view] and I can send mails to Hotmail, Gmail, etc. But I am receiving relay error when sending back from Hotmail, Gmail to my server.

After hours trying to fix this error, I guess I need an expert.

Skills: Apache, Linux, System Admin, UNIX, Web Hosting
