If you’ve ever gotten an email “from yourself”… and you realized it was spam, then you’ll appreciate why SPF (Sender Policy Framework) and SenderID are the new buzz in anti-spam and email authentication efforts. I do not pretend to be an expert on this topic. But here are some useful links you can follow to learn more: SPF site; article by Anne Mitchell in ClickZ: SPF: It’s not just a good idea ; and the DMA’s (Direct Marketing Association) backgrounder on email authentication. Stay tuned for more about what you need to know to both understand and stay in compliance with these new technologies. Oh, and don’t go phishing this summer.
