DomainKeys" creates a domain-level authentication framework for email by using public-key technology and the DNS to prove the provenance and contents of an email. This document defines the base framework of digitally signing email on a per-domain basis. Subsequent documents leverage this base framework to prove and validate email delivery paths as well as extend signing to facilitate per-user authentication. The ultimate goal of this framework is to unequivocally prove and protect identity while retaining the semantics of Internet email as it is known today. Proof and protection of email identity may assist in the global control of "spam" and "phishing". Delany Expires February, 2005 [Page 1] Internet-Draft DomainKeys August 2004 Table of
