Sender Policy Framework (SPF) Authentication Failure Reporting
Using the Abuse Reporting Format
Abstract
This memo presents extensions to the Abuse Reporting Format (ARF) and
Sender Policy Framework (SPF) specifications to allow for detailed
reporting of message authentication failures in an on-demand fashion.
This memo updates RFC 4408 by providing an IANA registry for SPF
modifiers.

1. Introduction
The Abuse Reporting Format [ARF] defines a message format for sending
reports of abuse in the messaging infrastructure, with an eye toward
automating both the generation and consumption of those reports.
The Sender Policy Framework [SPF] is one mechanism for message sender
authentication; it is "path-based", meaning it authenticates the
route that a message took from origin to destination. The output is
a verified domain name that can then be subjected to some sort of
evaluation process (e.g., comparison to a known-good list, submission
to a reputation service, etc.).
This document extends [SPF] to add an optional reporting address and
other parameters. Extension of [ARF] to add features required for
the reporting of these incidents is covered in [ARF-AUTHFAIL] and
[ARF-AS].
This document additionally creates a an IANA registry of [SPF] record
modifiers to avoid modifier namespace collisions.
