+                         Digest Message Format
+
+Status of this Memo
+
+   This memo describes the de facto standard Digest Message Format.
+   This is an elective experimental protocol.  Distribution of this memo
+   is unlimited.
+
+Background
+
+   High traffic volume large mailing lists began to appear on the net in
+   the mid-70s.  The moderators of those lists developed a digest
+   message format to enclose several messages into one composite message
+   for redistribution to the mailing list addressees.  This format
+   reduces the mailer load in proportion to the number of messages
+   contained within a digest message, and conserves network bandwidth by
+   reducing the size of the headers of the enclosed messages.
+
+   This RFC documents the digest message format so that others may
+   follow this format in creating (digestifying) and separating
+   (undigestifying) digest messages to maintain compatibility with the
+   programs expecting this de facto standard.  Any editorial functions
+   performed at the discretion of a digest moderator, such as discarding
+   submissions, editing content to correct spelling and punctuation
+   errors, inserting comments, and reformatting paragraphs to conform to
+   width conventions are beyond the scope of this memo.
+
+   This memo describes the de facto standard Digest Message Format.  It
+   is not meant to supersede nor replace the generic message
+   encapsulation format described in RFC 934.  It merely documents a
+   particular message encapsulation format that existed well before RFC
+   934 was published and continues to be the format of choice for digest
+   messages.
+
+Description
+
+   A digest message is a conventional message consisting of a header and
+   body conforming to RFC 822 as clarified in RFC 1123.  There is no
+   fixed size.  Limitations may exist in intermediate mail gateways
+   which restrict the size.  The typical digest size is 15,000
+   characters.
+
+   The header of a digest message should identify the digest in the

+RFC 1153                 Digest Message Format                April 1990
+
+
+   Subject line by listname, the key word, Digest, the volume number
+   (usually a sequential number either starting at 1 or the last two
+   digits of the year and incremented by one starting with the first
+   issue of the next calendar year), and an issue number starting at one
+   for the first issue of a new calendar year.
+
+   The body of a digest message must consist of a Preamble, one or more
+   enclosed messages, and a Trailer.
+
+   The Preamble usually contains a table of contents consisting of the
+   subject line contents of the enclosed messages, usually indented or
+   centered, and also may contain brief administrative or other
+   announcements.
+
+   The Preamble must be separated from the remainder of the message by a
+   line of 70 hyphens followed by a blank line.
+
+   Each enclosed message is a conventional message consisting of a
+   header and body, separated by a blank line.  If they exist in the
+   original message header, the following lines must be retained as-is
+   in the reconstructed header: Date:, From:, To:, Cc:, Subject:,
+   Message-ID:, and Keywords:, rearranged to appear in that order.
+   Retaining the Summary: line is optional.  Lines include continuation
+   lines as defined in the RFCs.  All other header lines should be
+   discarded, especially Received lines.  All leading and trailing blank
+   lines should be removed from the message body.  The message body may
+   be scanned to replace with a blank the first character of any lines
+   of exactly and only 30 hyphens.
+
+   Each enclosed message must be separated from the the remainder of the
+   digest message by a blank line before and after a line of 30 hyphens.
+
+   The Trailer immediately follows the blank line of message separator
+   following the last enclosed message.  The Trailer consists of two
+   lines.  The first line must begin with the words, End of, followed by
+   the listname a blank and the word Digest which is usually followed by
+   volume and issue number on the same line.  The second and last line
+   of the Trailer and the entire message is a line of asterisks serving
+   to underline the line immediately above it.
+
+Example
+
+   The following example serves as a template for a digest message
+   conforming to this memo.  It contains a header, and a body consisting
+   of a Preamble, two enclosed messages, and a Trailer.  fqhn means
+   Fully Qualified Host Name.  The Date: lines are examples only.
