In any event, I suggested "Author" because it is simple and accurate. Something like what you suggest - on the off-chance you are serious -- offers distracting tone and baggage. > when enough systems do mutant DMARC to cause the same problems with > Really-From that we have with From, That's a premise with no foundation and arguably no validity. At the least, if you are going to use this as the substance of your concern, perhaps you could explain with some care why you are so certain this will happen. Here's why I think it won't: They already have From:. The real value in DMARC is not what is displayed to the end-user but in having a required field that cites the originating domain name. That doesn't change if there are additional fields that might or might not mention the originating domain. > 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 The question of whether any MUAs will implement this is the same concern for any proposal. So on its own, that would mean we never do anything unless implementers and operators promise to use it.

It has it's own problems. There's no perfection here, since the task is retro-fitting work-arounds to an established mechanism that has been altered. As I've noted, realistically, DMARC makes the From: field be the Sender: field. d/ -- Dave Crocker Brandenburg InternetWorking bbiw.net
