No, the spam problem comes from accepting messages from people you don't
already know. This is of course a necessary feature of mail which is what
makes spam so hard.

(Actually not just that - it also comes from accepting messages from
people you sort-of know but who don't care about wasting your time, such
as corporate marketing departments.)

Your federated authentication idea is pretty neat, and could be the basis
of a better way of classifying mail from people you know or sort-of know.
