Can anyone help me? Our Exchange 2000 server is being used to relay SPAM in massive amounts and we can't seem to get it stopped. It is a Win2k server. We are in process of getting all our security patches up to date, but we have almost all of them done already and are still being used. We also went to MS website and printed their instructions on dealing with the problem, but it didn't take care of it. ?? Help?

There is an SMTP problem with W2K that you should be getting a fix for. We use Exch 5.5 and stop most relaying in the IMC properties by choosing the Reroute option and not listing any servers allowed to route. Check back after your patches are done.

Exchange, by default, enables the open relay function. Senders of spam search for these open relays servers for sending their spam. To stop this, you'll have to close the open relay.

See this link for a very thorough article on that subject.

Included in the article is a section describing how to Configure Internet Mail Connector To Stop Open Relay.
