I was told by my SMTP relay provider that my SBS 2003 server was relaying large amounts of spam messages. I checked and I am not an open relay. I could find the messages in my Message Tracker and in the Exchange logs. Attached is a spreadsheet with some of the spam messages. The "client-ip" is not mine. How do I find out where this is coming from and how do I block it?
