        Registration of Military Message Handling System (MMHS)
                 Header Fields for Use in Internet Mail

Abstract

   A Military Message Handling System (MMHS) processes formal messages
   ensuring release, distribution, security, and timely delivery across
   national and international strategic and tactical networks.  The MMHS
   Elements of Service are defined as a set of extensions to the ITU-T
   X.400 (1992) international standards and are specified in STANAG 4406
   Edition 2 and ACP 123.  This document specifies message header fields
   and associated processing for RFC 5322 (Internet Message Format) to
   provide a comparable messaging service.  In addition, this document
   provides for a STANAG 4406 / Internet Email Gateway that supports
   message conversion.
