The different bits in the message are simple enough.  

The problem is that it might as well be called Really-From, and then
when enough systems do mutant DMARC to cause the same problems with
Really-From that we have with From, the step after that is
Really-Really-From, so on ad nauseam. While that happens (or maybe
doesn't) we have no idea whether MUAs will display it or let you enter
it or automatically make it the same as From or maybe something else,
likely making it a disaster for interoperability.

I think the DMARC sender draft is a lot more promising.

R's,
John
