MH Michael Hammer (5304):
If a domain chooses to sign DKIM with respect to a From field email
address that purports to be from that domain and that domain has the
ability to make an assertion (of any sort) through SSP with regard to
it's practices:
Is the potential benefit afforded a receiver by checking that SSP
assertion AND taking whatever (unspecified) action worth the effort of
doing so? If receivers are likely to have little or no benefit/interest
in checking SSP then the rest of the discussion is moot.
In other words, is the juice worth the squeeze?
Spammers can use DKIM and SSP too. Therefore and the juice is not
worth the squeeze unless the receiver actually knows the domain.
Perfect DKIM+SSP by a total stranger is relatively meaningless.
But we've already visted that station many times in the past.
