- Title: Mapping between X.400 and RFC-822 Message Bodies

-
- Recently, the Internet Engineering Task Force (IETF) developed a
- document called, "Multipurpose Internet Mail Extensions" or MIME (RFC
- 1341). The title is actually misleading. MIME defines structure for
- Internet message bodies. It is not an extension to STD 11, RFC 822.
- Independently of this, the International standards community developed
- a different framework in 1984. This framework is known as the OSI
- Message Handling System (MHS) or sometimes X.400.
-
- Since the introduction of X.400(84), there has been work ongoing for
- defining mappings between MHS and RFC 822. The most recent work in
- this area is RFC 1327, which focuses primarily on translation of
- envelope and headers. This document is complimentary to RFC 1327 as
- it focuses on translation of the message body. The mappings defined
- are largely symmetrical with respect to MIME and MHS structuring
- semantics, although the MIME semantics are somewhat richer. In order
- to provide for reversible transformations, MHS heading extensions are
- used to carry the additional MIME semantics.
-
- 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.
- Distribution of this memo is unlimited.
-
- This announcement is sent to the IETF list and the RFC-DIST list.
- Requests to be added to or deleted from the IETF distribution list
- should be sent to IETF-REQUEST@CNRI.RESTON.VA.US. Requests to be added
- to or deleted from the RFC-DIST distribution list should be sent to
- RFC-REQUEST@NIC.DDN.MIL.
-
- Details on obtaining RFCs via FTP or EMAIL may be obtained by sending
- an EMAIL message to "rfc-info@ISI.EDU" with the message body
- "help: ways_to_get_rfcs". For example:
-
- To: rfc-info@ISI.EDU
- Subject: getting rfcs
-
- help: ways_to_get_rfcs
-
- Requests for special distribution should be addressed to either the
- author of the RFC in question, or to NIC.INTERNIC.NET. Unless
- specifically noted otherwise on the RFC itself, all RFCs are for
- unlimited distribution.
-
- Submissions for Requests for Comments should be sent to
- RFC-EDITOR@ISI.EDU. Please consult RFC 1111, "Instructions to RFC
