Sender Policy Framework (SPF) for Authorizing Use of Domains in E-Mail, Version 1  M. Wong, W. Schlitt April 2006 ASCII Errata  EXPERIMENTAL
E-mail on the Internet can be forged in a number of ways. In particular, existing protocols place no restriction on what a sending host can use as the reverse-path of a message or the domain given on the SMTP HELO/EHLO commands. This document describes version 1 of the ender Policy Framework (SPF) protocol, whereby a domain may explicitly authorize the hosts that are allowed to use its domain name, and a receiving host may check such authorization. This memo defines an Experimental Protocol for the Internet community.
