Just a thought. I keep thinking that Yahoo's publishing of their "p=reject" policy, and the subsequent massive denial of service to lost of list traffic might be viewed as a "computer security" incident. Anybody think that reporting via CERT channels might be an appropriate response? (I do, and probably will - but curious what others think.)

I would recommend reading these two blog entries first: http://yahoo.tumblr.com/post/82426971544/an-update-on-our-dmarc-policy-to-protect-our-users and http://yahoomail.tumblr.com/post/82426900353/yahoo-dmarc-policy-change-what-should-senders-do Then, I would ask--if the situation is deemed CERT-worthy, what is the emergency the community is being asked to respond to? Is it that Yahoo has decided, after many years, to start taking action to tighten down email abuse? Or is the emergency that too many mailing lists operate fast-and-loose with email headers, and that we as a community need to take swift and immediate action to fix mailing lists to correctly identify and attribute the true source of messages from the lists? My internal guess, based on the years and years of griping about forged sender spam that I've seen on this list, among others, is that the latter case is the emergency to which you are seeking a call to action. Thanks! Matt
