Hi Qusai,
Are you using any kind of router. If so, the MTU needs to be 1492 bytes or 
greater for your mail to go out. If not, it's going to stay there, and won't 
deliver your messages. I hope this help.

I check the relay option in SMTP virtual server and every things seems ok. 

Any help will be appreciated
