It smells of magical belief to me. Just sprinkle on some public key fairy

a scheme would offer which something like SPF/LMAP wouldn't.
Slightly lower administrative costs, perhaps. Possibly better
ability to transit mailing lists.
Another difference here is that LMAP addresses MAIL FROM forgery in the
SMTP transaction, while DK addresses forgery in the mail headers and
email message itself.
The drawback is you can't delegate authority like you can in LMAP.
What about if you use subkeys?
