The RDNS check in XMail is a simple "does this IP address have a PTR record", as far as I know. I've done some additional coding to test the returned DNS name against a list of known spam DNS names on my own system... - To unsubscribe from this list: send the line "unsubscribe xmail" in the body of a message to [EMAIL PROTECTED] For general help: send the line "help" in the body of a message to [EMAIL PROTECTED]
