Starting around 5:20am CST on 05.22.07 it looks like a spammer is using my domain name as the From: field in their spam. I had a catch bucket turned on for the domain and in less than 30 minutes I got around 1000 bounce notices. Had I had the bucket turned off I never would have seen them doing this.
I wish there were something I could do about this, but there isnt. The mail isn’t going through my server at all. I’m only being refrenced in the From fields. See Wikipedia Email Spoofing and Joe Job Like Automated Spam
