sql server database mail error

I had configured database mail, but got this error when testing. this was sql server 2008

The mail could not be sent to the recipients because of the mail server failure. (Sending Mail using Account... Exception Message: Could not connect to mail server. (No connection could be made because the target machine actively refused it.)

First you should make sure that you are able to telnet the mail server from the sql server machine on port 125.

(C:\>telnet mail_server 125) if this fails you should check with your network admin.

 Sometimes this error is thrown if the server cannto relay mail off the mail server. Your mail admin can help with that. Also, it would not hurt to determine the security on the connection. For example, if the connection requires SSL you can add that functionality on the appropriate mail profiles. HTH.
