SPF is only going to address one form of spam distribution. Unfortunately it does nothing for the spammers who get their own domain and establish their own SPF records. They can continue to spam away at will. Likewise SPF will not close any of the open relays run by the organizations that are pushing SPF. Those will continue to forward spam like they do today. I suspect the open relays are ahead of their SPF checking as we continue to receive mail through them even theough they claim SPF is in use. Spam will only go away when people no longer respond to it. When there is no revenue generated to cover the cost of spamming then it will end. Since spamming is so cheap, it only takes a couple of responses to cover the costs. Probability of finding a couple of morons out there is 1.00. People still respond to the Nigerian scams.....
