Yahoo! Develops Anti-Spam Architecture

prostoalex writes "Yahoo!, the owner of one of the largest e-mail systems in the world, is said to be developing a cryptographic product that will be offered freely to mail servers. 'Domain Keys,' according to the Reuters article, would require the message sender to authenticate in order for message to come across a trusted e-mail network. The idea has been around for ages, however, it required someone from the big league like Yahoo! to step in." While Yahoo! isn't the first name that comes to mind when I think of trusted email, it's still a step in the right direction.

What do they mean... sends a private key?

[Saint Stephen]

Obviously they must mean something besides the traditional notion of "private key" when they say "a private key is sent in the header, and the public key is used to decrypt it".

Is this a mistake, or is there some other terminology this is following?
