DK or IIM makes it clear who is administering the server and this authentication permits reputation assessment. Add an account identifier, and the problem is nailed.Ah, so you're saying that only the reputation of individual e-mail addresses is worth paying attention to? How do you expect that to scale to billions of messages per day?
Isn't that called S/MIME and PGP? It hasn't scaled yet. I've received two S/MIME messages in my life, and a few more PGP messages. A problem is if the computer has been compromised, its likely the authentication information stored on the computer has also been compromised or will be when the user starts typing any missing information. Very few consumer-grade computers have advanced security devices installed. As I keep saying, a secure computer rarely DDOSes, spams or sends viruses. And when they do, its much easier to whack the owner. So how do we keep computers secure and fix the insecure ones?
