No, This is on the Server level, just like R'otica. I don't block anyone except spammers and then it goes to a catch all spam folder on my account so I can sort through things. About 50% of the mailings from Renderotica and Renderosity don't even make it to the spam folder. I still get certain things like forum notifications and sales receipts from R'otica. But newsletters don't even make it that far. Lillian even check my account here a couple of months ago and everything was fine on this end.
