Hi, that's probably a stupid question, sorry. The drafts... draft-schlitt-spf-classic-00.txt draft-lyon-senderid-core-00.txt ...have been both sent to "dea-dir". I've no idea who this is. They document different experiments (SPF and Sender-ID). The second experiment would corrupt the first experiment by (ab)using the same data. It offers a way to opt-out of the second experiment, but the about 750,000 participants [1] of the first experiment don't all know this, the second experiment was started almost a year after the first. As a result mails will be handled as "spam", which are in fact no spam. All that has to be done to split these experiments is to remove chapter 3.4 from the second text, i.e. draft-lyon-senderid-core-00.txt This was also some kind of "rough consensus" of the former MARID WG [2], the dubious chapter 3.4 is a later addition by the authors of the secod draft. Maybe the coauthor M. Wong of both drafts could help to clarify this confusion. Bye, Frank [1] 750,000 is a claim by an early adopter of the 2nd draft [2] "rough consensus" as identified by the former WG chairs Posted on ietf-general and (only for info) on spf-discuss _______________________________________________ Ietf@xxxxxxxx https://www1.ietf.org/mailman/listinfo/ietf
