In 2006, the IETF published a suite of protocol documents comprising
the Sender Policy Framework (SPF) and Sender ID: two proposed email
authentication protocols.  Both of these protocols enable one to
publish, via the Domain Name System, a policy declaring which mail
servers were authorized to send email on behalf of the domain name
being queried.  There was concern that the two would conflict in some
significant operational situations, interfering with message

The IESG required all of these documents (RFC 4405, RFC 4406, RFC
4407, and RFC 4408) to be published as Experimental RFCs and
requested that the community observe deployment and operation of the
protocols over a period of two years from the date of publication to
determine a reasonable path forward.

After six years, sufficient experience and evidence have been
collected that the experiments thus created can be considered
concluded.  This document presents those findings.  This document 
is not an Internet Standards Track specification; it is
published for informational purposes.

This document is a product of the SPF Update Working Group of the IETF.
