Get over the concept of using SPF as a validation of anything other than the address from which the email was sent. Spam filters still have the responsibility to validate THAT address against spam address lists. SPF may make this easier because forged addresses go away. That means botnet spamming will probably cease as well. But the spam filters still need to decide if a given "yes, indeed, it came from this location" email is from a spammer location or not. {^_^}
