Sender ID: Authenticating E-Mail
RFC 4406, “Sender ID: Authenticating E-Mail”, is a Historic document published in April 2006 by J. Lyon, M. Wong. The canonical text is published by the RFC Editor.
Abstract
Internet mail suffers from the fact that much unwanted mail is sent using spoofed addresses -- "spoofed" in this case means that the address is used without the permission of the domain owner. This document describes a family of tests by which SMTP servers can determine whether an e-mail address in a received message was used with the permission of the owner of the domain contained in that e-mail address. This memo defines an Experimental Protocol for the Internet community.
What “Historic” means
