I guess I'm one of those mail admins who is behind the times. But I don't really care that much because I take the same position as Suresh Ramasubramanian... that SPF is a failed technology because, for one, it breaks e-mail forwarding and there are ALWAYS too many legit e-mail forwarding situations (and legit substitutionary "from" situations--like sending from one's phone) to create problems in comparison to the problems that SPF solves. The ONLY exception is when enduring a severe "Joe Job" attack. In THAT situation, a strong SPF record will disrupt much of the spammer's messages, and cause them to switch to OTHER forged "from" addresses. In that situation, SPF is your friend. Otherwise, it is more trouble than its worth, imo. Because many feel this way, I suspect that this may be the reason why the lastest and greatest SPF support probably wasn' a huge priority for SA? -- Rob McEwen http://dnsbl.invaluement.com/ r...@invaluement.com +1 (478) 475-9032
