Yes.  I specifically said this, and many said "you will still be marked 
as a spammer", but I am not.

RFCs also say to bounce an email sent to a non-existent user.  These

yourself marked as a spammer (since you will bounce to the forged From: 
address, which is the real adddress the spammer wants to spam).
