Identifying the sender reliably is the missing link in the current

The missing link is really 2 different problems depending on which
side of the link you are on. The receiver can't identify the actual
sender and the smarthost can't reliably identify the email as
abusive. Providing direct feedback when email is abusive (such as
when unsolicited email hits a spamtrap) could bridge the gap and
permit the smarthost to take appropriate action to stop the abuse.
DKIM and ARF between them provide all the protocol-level solution
needed for that. DKIM was the missing link I was thinking of.
Cheers,
