I mean what benefit would a receiver enjoy over not implementing it at
all?
It would be a spam filter basically. Being an anti-forgery protocol, it
would have a high false negative rate compared to dedicated anti-spam
techniques (since unforged spam definitely exists), but it would offer a
very low false positive rate.
Turning it on for all users by default would be even less controversial
than turning on, say, Spamhaus ZEN.
Except for the mailing-list-footers case and the traditional-forwarder
case, no wanted mail is forged. And "EDSP" would not trigger on those
two cases.
