John,
the domain owner is whoever has control over the RRs
in the DNS, that are associated with the domain name.

well, i was taking 'domain ownership' as the term already in use, but i
agree that it's better to drop the term and just talk about contents of
the RRs associated with the domain name.
Authentication Verifying the Identity (TCP sequence numbers)
Authorization Domain owner's statement
Which domain?
HD> The domain given in the sender's address (or whatever part of the
HD> message. That who's held responsible in case of spam).
I suggest we eliminate use of the word "sender", except as part of the
term "RFC2822 Sender". When used without qualifiers, the term "sender"
is now ambiguous. So which, exact, field provides the domain string on
which authorization is based?
