When I identify a spam message, I return a message to the sender indicating "bad address". Eventually, their server will remove my address from their list in order to better utilize their bandwidth. There are a few false positives and I'll need to add an exception rule.
Do you mind going into detail about this “bad address” email you send out? What does it look like, images or what not, formate and what does it say?
