Exchange 2003 open-relay
I am running server 2003 sp2 with exchange 2003. I have a webmaster account that seems to be sending out spam. The password has been changed, but it seems more like a open-relay type situation. The message queues have multiple messages that are trying to go out that are spam.
How do I stop this from happening?

You are welcome - hopefully if it is just a case of NDR spam and all you had was Administrator mail going back to spammers, you should be fine, but please check www.mxtoolbox.com/blacklists.aspx and make sure you haven't landed on Backscatterer.org.
