I had this Openrelay problem yesterday and had it solved by

Soekratis and Anna777, but I had problem with my browser awarding techpoints.

I would be grateful to award the techpoints, should both above named persons reply, by re-posting answers.

Here goes...

First and foremost, disable the "domain guest account" in NT.

The Internet Mail Service may allow non-authenticated users to relay mail using your Exchange Server if the Windows NT domain Guest account is enabled. Some clients will attempt to use the guest account when SMTP authentication fails. This allows them to bypass routing restrictions that require authentication

you can further increases the security by applying routing restriction. Open the properties of the IMS, click the Routing tab, and then click the Routing Restrictions button.

To Darlington,

I think you have allocated more points than it originally was.

Here's my original answer. I'm glad it helped.

"Your Exchange server must be at least at Service Pack 1 for you to have the Routing Restrictions button. See Microsoft KB articles Q199656 and Q199626, for more details."
