Abstract

[AUTHRES] defined a new header field for electronic mail messages that presents the results of a message authentication effort in a machine-readable format. Absent from that specification was the means by which the results of two cryptographic signatures, such as those provided by [DKIM], can both have results reported in an unambiguous manner.

Abstract
