Where can I enable the SMTP authentication in Exchange IMS?

My ISP SMTP relay required user authentication, How can I enable in MS Exchange Internet Connection Service?

On the SMTP virtual server properties, go to the delivery tab, outbound security button. That's where you would enter that information.

Is there a particular reason that you want to do this -- just becarefull because there are a lot of Denial of service attacks for smtp auth.......
If his ISP requires authentication, I have to believe he's going to need to put that in here. Inbound is where the auth attacks take place, not outbound from the Exchange server.
