Can't connect to mail server

I got this message bounce back when I try to send a message to my mail box at my new server. Do you know how to solve?

I can send mail from my server to outside address and inside address. But can't send mail to my server. Plus, my Outlook can't connect to POP/SMTP at my server.

Code:
