Exchange 2007 Receive Connectors
Posted on 2009-07-02
I have inherited an exchange 2007 server with two receive connectors setup, both using anonymous user permission groups. One connector is for SQL mail, and the other is for a custom website on my webserver. I have recently noticed SPAM that I believe to be exploiting this vulnerability, however I'm not sure what the best way to go about securing these receive connectors would be. I am reaching out for some advice on this issue if anyone can provide.
