To be fair to Mr. McCarron, having muddled my way through his accusations against ASRG and life history, the basic idea of his scheme¹ is simple and appears sound; when DKIM was later standardized it would achieve the same result (albeit by cryptography rather than a simple token check). Unfortunately, he seems to have missed the idea of just adding a new envelope header and SMTP command, and instead gone the route of throwing the baby out with the bathwater and reinventing not only the wheel, but quite possibly the concept of circularity itself. Not only was GEIS to have replaced SMTP (in an entirely incompatible way), but he even went so far as to declare that “all 'GIEIS' servers will run on a separate transmission protocol (not TCP/IP).” Add to that protocol megalomania some impenetrable architecture diagrams, a curious bit of Egyptology, self-admitted arrogance, and a very suspicious bit of sock-puppetry, and it's no wonder that the Register gave him such a send-up. ¹(include a nonce when sending an email, which the recipient can check with the originating server to confirm that the email is genuine)
