There must be a good reason for people to get of their asses and start implementing things like DMARC. All the banks (!$%^) I talk to do not have any reason to implement it swiftly (they turn on p=none and then all progress stops). Frustrating that they are too lazy to implement a few DNS records. It only needs firm backing by 3+ large companies like Hotmail. Give everyone on IPv6 without DMARC a large spamscore (and publish that beforehand ;-) ). Give me ammunition and all corporates will move.
Please no. DMARC is great for 1:1 direct email (from:me, to:you). Anything other than p=none fails miserably once the scope is expanded. Let me give you examples of things that would fail miserably under your suggestion above: 1) This list 2) The recent, heavily forwarded and reflected, Cisco PSIRT notices. NANOG is not the place to debate this, nor is it the place to advocate self inflicted harm. -Jim P.
