Hello, I am currently involved in a project to create an internet-draft for a domain/key based system allowing mail domains to be validated using rsa keys, distributed using the DNS system, with minimal modification to existing infrastructure. Does a specification for such a system already exist? I have many ideas for extentions to the existing SMTP protocol, as well as plans for a derivative protocol incorporating this key-based system as a more secure and verifiable method of exchanging mail. If anyone is interested, I would appreciate being contacted off-list to discuss the possible formation of a working group to discuss such ideas.
