The problem lies with email servers assuming that a mail server will receive mail on port 25. I fixed the issue. Emails are now coming through.

With a relay it doesn't really matter how you configure postfix, so just configure postfix to run like this:

Also, I believe that if you're not using a relay, the above setup should still work. My understanding is that port 25 is used for incoming connections while submission port (587) is used for outgoing mail IF you configure postfix to use the submission port. Please correct me if I'm wrong.
