Worked for me. I saw a snippet on the web somewhere, giving that email address and suggesting what I did. I have no idea what goes on at the other end, they don't acknowledge or anything. Maybe that address is attached to a machine like Bill Shackelford's.
But slowly, over months and months, the spam tapered off.
Thinking more about it, I was wrong. I was sending the whole header of each email, after removing the body, so they could possibly mine hidden(from me anyway) information. Sorry to mislead you.
Since I don't know what was going on at their end, there's no way of knowing exactly what they want. But by passing them on every day, they see frequency as well, I guess.
They might work on bulk, like having a chat with the biggest offenders.....not on the administrations donor list.
It could also just be coincidence like 24 beers in a case. But, it was strangely satisfying to do something,
anything, and like a wise man once said.....can't hurt.
