        RFC 1327:

        Title:      Mapping between X.400(1988) / ISO 10021 and RFC 822
        Author:     S. Hardcastle-Kille
        Mailbox:    S.Kille@CS.UCL.AC.UK
        Pages:      113
        Characters: 228,598
        Obsoletes:  RFCs 987, 1026, 1138, 1148
        Updates:    RFC 822

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), and systems using the RFC
822 mail protocol 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 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.

This is now a Proposed Standard Protocol.

This RFC specifies an IAB standards track protocol for the Internet
community, and requests discussion and suggestions for improvements.
Please refer to the current edition of the "IAB Official Protocol
Standards" for the standardization state and status of this protocol.
