Die Spam Die....
The sad thing is, this is spam from spam blockers. Does it really do any good? I never take any stock in it. Seems some jackass decided to use @[one of my domains].com with fake addresses to send out spam, causing me to get over 20 return "This address does not exist" or "This message has been blocked because it is spam" emails. I need to find out more about this company that is sending out this spam and see if I can sue them for the time they took from me, and the time it took to track them down and sue them.
I sent a legal threat to the owner of the domains, I stopped getting the returns, just goes to show you, a little effort can stop spam.
Been spam free since that legal threat. Fight the spam!
