Well, sort of - given that DMARC is still an Internet draft, not even an
experimental standard. Maybe it's doing what the draft says it is - but
it's an alpha-level protocol, that breaks a lot of things it touches.
If not "broken" it's certainly "not ready for prime time" - and large
scale deployment is akin to a DDoS attack - i.e., not "ill-advised" but
verging on criminal.
