Although that's useful for some situations it's a not at the heart of the spam problem, or is just one small facet at best. People you don't know, like perhaps me right now, will send you email which isn't spam, and which presumably you're ok with receiving. So, it's not the overriding problem with spam.

And I insist that we are all wasting our time trying to make SMTP and its supporting protocols (and their kin under IPX/SPC, Sperrylink, UUCP, et alia) are not at the transport layer and nothing at the transport layer is responsible for nor rich with solutions for their problems.
IF the overriding problem is due to an inability to identify and authenticate the identification of the sender, then let us work on establishing a protocol for identifying the sender and authenticating the identification of the sender and permitting the receiver to accept or deny acceptance of traffic by reference to that identification.
