Draft, section 5 suggests that a header is added to messages that are successfully authenticated.
o Add a header field, recording the result. If no MAC is provided, or the MAC is invalid, the server may require a hash cash transaction, and it should delete any possibly faked header in the incoming mail, that says the MAC was valid.
Any ideas on what the header should look like?
