things when talking about books. An author creates a book. A publisher
introduces the book to the world in a presentable format. A Bookstore
make the book available to the public. Using Bill's suggestion:
email           books
author          author
originator      publisher
operator        bookstore

I noted your earlier use of 'publisher' and it bothered me quite a bit.

However  I am warming to the model you describe.

1. It is an extremely well-established model.

2. It pertains to salient responsibilities in an information transfer sequence.

(Given that multiple operators can be in a sequence, I'd suggest 'distributor' rather than 'bookstore'.)

It scares me quite a bit to have my email operator be vested with apparent responsibility for the content of my email, but, alas, I guess that really is what the anti-abuse work is about.

What do other folks think?

DKIM is not about defining the author of the message and would conflict with the charter. Only when the signing-domain coincides with that of the email-address, are _assumptions_ possible. Assignment of accountability does not scale down to the user, and DKIM itself offers no protection beyond the domain. Rather than seeing this as a trail that starts with the author, these roles are better broken down into MTA functions that have already been established, MSA, Mediator, MDA.
