Exchange server is unable to relay but still sends spam
Posted on 2004-08-23
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?
