I wasn't writing about their website, rather the motivations of the
core participants of the DMARC spec (that hang out around that
website).   If you haven't been paying attention all along, it's easy
to miss the changes from the original DMARC objectives.  Sometime
after the first draft, DMARC went from only being for transactional
email (i.e. behind the scenes stuff), to full blown end-all of spam
with DMARC appearing on every tech blog and even CNN.  That train's
been barreling down the track for some time now.

I posted this earlier, but for refresher:

Go here:
Notice the early versions of the spec contained the word
"transactional", notice the current version has it removed.   Also
notice that (at the point of change) one of the authors is from Yahoo!.

What Yahoo! did wasn't a fluke, nor independent happenstance, it's
part of a much bigger and broader picture.

The ironic thing is that rather than go the IETF way (a fair amount of
the DMARC folk are past IETF contributors), the decision was made to
not seek peer consensus, nor to invalidate conflicting RFCs.  An end
