Cannot send mail ?

From this afternoon, our email server cannot send mail to outside, but can receive mail .

And I can send me to myself.

How can I do ?

What error do you get?What has changed? You have a new firewall? Loose network connection?Can you telnet from your box to an external mail server on the smtp port (25), and get a connection?It's HIGHLY unlikely that the server has caused this.
