Technical Summary
In 2006 the IETF published a suite of protocol documents comprising
SPF and Sender ID, two proposed email authentication protocols with
Experimental status. After six years, sufficient experience and
evidence have been collected that the experiments thus created can
be considered concluded. This document presents those findings.
Working Group Summary
The SPFBIS working group had a difficult task ahead as it was not clear
how to conclude the SPF and Sender ID Experiments and how to address
the IESG Notes in RFC 4405, RFC4406, RFC4407, and RFC4408. There were
discussions about how to proceed. Only one proposal was submitted and
it was adopted by the working group.
The discussions about the RRTYPE 99 DNS Resource Record were controversial.
The issue was resolved. There was consensus that Sender ID re-use of
SPF DNS Resource Records does not have to be called out in the document.
This document represents a best effort by the SPFBIS working group to
conclude the experiments which were documented in the above-mentioned
RFCs.
Document Quality
The document does not specify a protocol. The document was reviewed by the
SPFBIS working group. Barry Leiba, as an individual, and Dave Crocker
performed a thorough review of the document.
