Primarily you're proposing a technical solution which requires global buy in for it to be particularly useful.
Your solution allows for the verification of a sender. It is useful for preventing people spoofing your address, but requires everyone to use it for verification in order to prevent you seeing blow back. It also doesn't let you be sure an email is verified rather than just from a domain without the verification support. And verifying senders won't actually cut out spam unless you only ever want to receive email from a whitelist of recipients.
While I do agree a standard way to verify email headers etc could be useful, I don't think it's going to kill spam.
