Well I have a fairly new Exchange 2000(1 month) install. All of a sudden in ths last week I have noticed my disk space getting smaller. After further investigation my Bad mail folder and the Queue folder are both filling with messages. If I look at some of the messages in the bad and que they are the famous spams(Viagra and all them nice emails). They are coming in from my SMTP Virtual Server. I looked in the properties and have no computers allowed to relay. The check box is checked that allows computers to relay who successfully authenticate. I have all 3 boxes checked in the authentication tab(Everything that was defaulted). I have tried unchecking the Anonymous access but then I start getting no emails. I have started putting IP addresses in my connection to reject IP addresses that I have noticed are relaying but I know you can't keep up with that plus that is a small bandaid fix. I am at a loss of why they are able to relay. I have checked my server via relay tests and the tests keep coming back that my mail server is not a relay server. Any help or pointers would be appreciated.
