John Levine, Chair, IRTF Antispam Research Group (ASRG) writes in his weblog that the anti-spam Sender Policy Framework (SPF) email authentication scheme is losing market mindshare.

In a recent talk at an ITU Cybersecurity Event, Mr. Levine gave a presentation entitled The Limits of Security Technology: Lessons from the Spam Wars. In his talk, he asked the audience to reflect carefully as to how technology fits in to the overall solution. He stressed that technology can be morally and politically neutral but we need to decide exactly what it is that we want. For example, an ultimate solution to spam could impact on issues such as anonymous speech, whether we wanted virtual or physical identities, or closed or open systems. These were all tradeoffs that needed to be considered.
