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.
