          Complaint Feedback Loop Operational Recommendations

Abstract

   Complaint Feedback Loops similar to those described herein have
   existed for more than a decade, resulting in many de facto standards
   and best practices.  This document is an attempt to codify, and thus
   clarify, the ways that both providers and consumers of these feedback
   mechanisms intend to use the feedback, describing some already common
   industry practices.

   This document is the result of cooperative efforts within the
   Messaging Anti-Abuse Working Group, a trade organization separate
   from the IETF.  The original MAAWG document upon which this document
   is based was published in April, 2010.  This document does not
   represent the consensus of the IETF; rather it is being published as
   an Informational RFC to make it widely available to the Internet
   community and simplify reference to this material from IETF work.
