Exchange 2003 smart host

[chilifrei64]

Anybody out there with Exchange Server experience

The ISP for one of my clients is sbc yahoo.

SBC Yahoo blocks outgoing smtp connections to other mail servers as their way or trying to reduce spam.

Exchange has a built in tool called an smtp connector which allows me to redirect outgoing smtp traffic to a smart host. I am allowed to make outgoing connections to sbcglobal.net

Here is my problem. I set up my smtp connector and suddenly all my emails send. Weather it is 3 or 50 emails, every email in the smtp queue sends. After that, the emails stop going out. The queue still shows that it is froze in the smtp connector, which means that messages are being redirected to the smtp connector but it is not sending them.

Obviously authentication works becasue it works once

I have smtp connector set to always run.

has anyone else ran into this problem or know of a fix.

Incase anybody is interested. I was able to get this working by setting authentication to anonymous. Apparently SBC allows for annonymous authentication on their TURNS/ETURNS server for smart hosts.
