Postix dosen't forward to Gmail Yahoo Hotmail

Postix dosen't forward to Gmail Yahoo Hotmail

I have a problem with my Postfix 2.8.4 (Cent OS 6 with Plesk 11.0)
If i sent an email to one of these providers, it will be delivered ok.
If I setup my email to forward all emails to one of these providers:
a. if i sent from an email from the same server, it will be delivered ok
b. If I sent from an email not hosted on the server, the mail will be
stuck in the queue forever.
Below is my main.cf
