I wouldn't compare SPF and SSP, they're mostly unrelated. For
a comparison of SenderID and SSP it's hard to judge, the "PRA"
concept makes more sense than looking only at the 2822-From.
On the other hand SenderID is based on an IP enumeration (like
SPF), and DKIM on a signature surviving almost everything excl.
"some" (= unfortunately almost all) irregular mailing lists.
If SSP sticks to the 2822-From as its method to identify some
kind of "authority" for _unsigned_ mails I think it's hopeless.
Phil's ideas about updating algorithms could still work, no
matter what the rest of SSP tries to achieve.
