It would be sufficient to build a web of trust of MTAs. Email from trusted MTAs would be forwarded ahead of email from non-trusted MTAs. Doing that alone would leave most SPAM sitting in queues *not* slowing down legitimate email. The "trusted-or-not" attribute may be fed into any spam-filtering machinery at any stage, as well.
DNS could be used to hold MTA ID signatures/keys, though private signature key-lists could be maintained by any cooperating group of MTAs. Heck, we used to do that much with UUCP maps, in some sense.
This is off-the-shelf technology. No patent-mongers need apply.
