I am running exchange 2000 sp3 and i have people who connect and try and send mail spam out. they are attempting to use me as a relay. i read an earier article on locking it down and only letting people who authenticate to send. The people who don't authenitcate's mail gets sent to the bad mail folder and stay in the queue?
When i check the sessions, i still see a number of people connected and do no understand why. is there a way to block them from connecting at all, even if the mail is just going to the badmail folder? this is using resources on my server.
i have esm....smtp....prop....relay....."allow only computers which successfully authenicate to relay" check marked.
If you look under esm.....prop....access control.....anonmous is checked. it is my understanding that this has to be check to allow mail from the outside in.
