Hi Varga,

What evidence do you have that someone is relaying through your server? Did 
your ISP or someone else tell you that was happening, or do you have a Netmon 
trace and SMTP logs confirming this is so?

Thanks!
Tom

        Hi Mark!

        I have read Your article again, but not for resolve my problem. I have 
read and I looking for word: firewall. (Result: there is not.) Why? Because 
relaying must be closed also on the firewall.
        Thanks for Your interest.

        Regards!

        Pavol.

Read my article again, if you follow all the steps then you wont be an open
relay anymore.

Varga

I am not sure from your message what the problem is, are you saying that you
are a relay?

        Hi all, specially skilled administrators!
        
        We have big problems with our open relay Exchange 2000. Yesterday
has occured this problem, and reason or solution is not known!
        I have read discussion list about open relay, tutorial by Mark
Fugatt "Understanding Relaying and ...", M$ KBs }310380, 310356, ...) ...
all that seems so easy!

        1) configure SMTP virtual server
        2) configure connectors

        But it doesn´t work!
        After all I think, that MMC doesn't work properly!
        How can I verity, that changes in MMC do real changes in registry?
        Or, is this a right-time for restore system state?!

        Thanks for any help leading to resolve my problem!

        Pavol.
