Hi guys, I have an issue. I configured my Mercury mail and it was working fine for a month. Today I logged in to my admin account and saw a ton of Mail delivery errors "Postmaster Notify: Delivery Failure." I had no idea what happened so I logged on to my server to check it out. The server was just spamming some crap back and forth starting minutes after the midnight.. There was 350k messages about some Mustafa .. anyway I googled that its a random scam.. But my question is HOW DID THIS HAPPEN? Any way to get rid of it? Currently my mercury mail server is down until I do something.
Also the log file was 25mb and it contains thousands of "rcpt TO:" enteries from an IP address that made 20 connections at the same time???
