Postfix Mail Forwarding: Socket Error ..How to fix MX records?

Hello –

I sent test messages from my personal gmail account to test if the mail forwarding is working ( which should work as all the configurations are in place, now), none of the test messages are delivered and this is what I see in the “mail delivery subsystem message”

“The recipient server did not accept our requests to connect. Learn more at http://support.google.com/mail/bin/answer.py?answer=7720 [(5) mail.yenidensen.com. [178.62.224.65]:25: socket error]”

And when I click on the support.google, I see below. Clearly, there is aproblem with the MX records, how do I get this issue solved, any ideas?

DO’s Support team cant help here.

‘The recipient server did not accept our requests…’

This error message means that we tried to reach the server of the person you’re sending an email to, but didn’t get a reply, so we couldn’t send your email. This could be a temporary problem, and we suggest you try again later.

You could also contact the customer service department of the other domain (the one you’re sending to). The problem might be because:

The other domain doesn’t have up-to-date MX records or is otherwise misconfigured. The other domain is blacklisting or graylisting messages from Gmail. The other domain has temporary networking problems.
