Re: Wot no SPF?
SPF is a pretty big joke. If you are (incorrectly) using it to outright block mail versus using it as a scoring system, you're going to get false positives. Using it as a scoring system, it holds so little weight, it barely factors in to the overall spam score. That combined with the fact that spammers can just as easily set up an SPF record to authorize mail from anywhere (but luckily they are generally not that smart), it's never really lived up to its original hype.
