Hi,

My problem is that i have an exchange server 2000 :-) . I've did a basic installation and disabled the relay option.
Tested this with telnet and yes my server was unable to relay. After couple of weeks i saw 200 domains in my smtp queue with let's say 2000 mails waiting to be sent. I looked in the current sessions display and saw an connection from somebody for over 3000 seconds. When I terminated this person and deleted my messages in the queue i saw a whole list appearing yet again and when i looked in the current sessions display I saw again a person from another IP adress. you can deny all those ip adresses but they are still appearing with new ip adresses and new names.

How can I stop this. Installed all windows updates and service packs for exchange...

What to do?

With regards,

Steven Oosterhuis

This really is the million dolar question.
I was able to significatnly reduce spam by enabling relaying for those email that originated from the server.
This setting is in the same place as where you disable the relay.
Try it.

Came up with it myself.
When you set your relay settings as they are told by Microsoft you have to select the option Allow all computers which successfully authenticate to relay, regardless of the list above  . And in exchange 2003 there was a anonymous user account which some people used to connect to my mail server and relay spam.....

:-) customer happy and I can sleep again... (Yawn)
