A Revised Internet-Draft is available from the on-line Internet-Drafts
directories. This draft is a work item of the Internet Message Extensions
Working Group of the IETF.
Title : Multipurpose Internet Mail Extensions (MIME) Part One:
Format of Internet Message Bodies
Author(s) : N. Borenstein, N. Freed
Filename : draft-ietf-822ext-mime-imb-01.txt
Pages : 100
Date : 11/22/1994
STD 11, RFC 822 defines a message representation protocol specifying
considerable detail about message headers, but which leaves the message
content, or message body, as flat US-ASCII text. This document redefines
the format of message bodies to allow multi-part textual and non-textual
message bodies to be represented and exchanged without loss of information.
This is based on earlier work documented in RFC 934, STD 11, and RFC 1049,
but extends and revises them. Because RFC 822 said so little about message
bodies, this document is largely orthogonal to (rather than a revision of)
RFC 822.
In particular, this document is designed to provide facilities to
include multiple parts in a single message, to represent body text
in character sets other than US-ASCII, to represent formatted multi-font
text messages, to represent non-textual material such as images and
audio fragments, and generally to facilitate later extensions defining
new types of Internet mail for use by cooperating mail agents.
This document does NOT extend Internet mail header fields to
permit anything other than US-ASCII text data. Such extensions
are the subject of [RFC-MIME-HEADERS].
This document is a revision of RFC 1521, which was a revision
of RFC 1341. Significant differences from RFC 1521 are
summarized in Appendix G.

Send a message to: mailserv(_at_)ds(_dot_)internic(_dot_)net(_dot_) In the
body type:
"FILE /internet-drafts/draft-ietf-822ext-mime-imb-01.txt".
NOTE: The mail server at ds.internic.net can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e., documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
