Abstract

   This document describes a set of mappings which will enable
   interworking between systems operating the CCITT X.400 1988)
   Recommendations on Message Handling Systems / ISO IEC 10021 Message
   Oriented Text Interchange Systems (MOTIS) [CCITT/ISO88a], and systems
   using the RFC 822 mail protocol [Crocker82a] or protocols derived
   from RFC 822.  The approach aims to maximise the services offered
   across the boundary, whilst not requiring unduly complex mappings.
   The mappings should not require any changes to end systems. This
   document is a revision based on RFCs 987, 1026, 1138, and 1148
   [Kille86a,Kille87a] which it obsoletes.

   This document specifies a mapping between two protocols.  This
   specification should be used when this mapping is performed on the
   DARPA Internet or in the UK Academic Community.  This specification
   may be modified in the light of implementation experience, but no
   substantial changes are expected.
