[RFC7001] describes a header field called Authentication-Results for use with electronic mail messages to indicate the results of message authentication efforts. Any receiver-side software, such as mail filters or Mail User Agents (MUAs), can use this header field to relay that information in a convenient and meaningful way to users, or make sorting and filtering decisions. One portion of the definition in that document limits the types of authentication properties about a message to a small, fixed set. This document updates the specification to allow new property types to be declared and used.
