Some spammer is using random email names @ my ltlfrari.com domain name as the return address for spam email. So every time it bounces I get the notification email and every time one gets through and the victim tells the sender to piss off, I get it, not the real spammer.
They also appear to be being sent from multiple ip addresses but since I am only getting either the bounced email, or a reply from some hapless victim I don't really get to see the complete original emails headers.
So, how the hell do I track this bastard down and stop him/her/it using my domain name. I'm assuming legal methods are a waste of time, I just want to be able to track the sod down to start with. I'll worry about what action to take later.
