Domain-Based Email Authentication Using Public Keys Advertised in the DNS (DomainKeys)
“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 a framework for digitally signing email on a
per-domain basis. 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”.
