                  The Multipart/Report Media Type for
          the Reporting of Mail System Administrative Messages

Abstract

   The multipart/report Multipurpose Internet Mail Extensions (MIME)
   media type is a general "family" or "container" type for electronic
   mail reports of any kind.  Although this memo defines only the use of
   the multipart/report media type with respect to delivery status
   reports, mail processing programs will benefit if a single media type
   is used for all kinds of reports.

   This memo obsoletes "The Multipart/Report Content Type for the
   Reporting of Mail System Administrative Messages", RFC 3462, and
   marks RFC 3462 and its predecessor as "Historic".

1.  Introduction

   [OLD-REPORT] and its antecedent declared the multipart/report media
   type for use within the [MIME] construct to create a container for
   mail system administrative reports of various kinds.

   Practical experience has shown that the general requirement of having
   that media type constrained to be used only as the outermost MIME
   type of a message is overly restrictive and limits such things as the
   transmission of multiple administrative reports within a single
   overall message container.  In particular, it prevents one from
   forwarding a report as part of another multipart MIME message.
