 From your note I thought you didn't know about the spec.  (No, that 
doesn't seem like a reasonable believe on my part, but I'm still working 
on my second cup of coffee.)


> In shorthand terms, Author is the opposite of Sender.  In the existing Sender paradigm From is constant, the mediator would add Sender, which would result in sent by Sender on behalf of From.  Under this proposal the originator includes both From and Author, the mediator mangles From and the result could be sent by From on behalf of Author.  Is that right?

One of the reasons I pointed to the draft is that it discusses the 
history and semantics of Sender vs. From and makes the case the DMARC 
forces From to be Sender, but not really From any more. Author seeks to 
recover a purely From semantic.
