The Multipart/Report Multipurpose Internet Mail Extensions (MIME)
content-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 content-type with respect to delivery status
reports, mail processing programs will benefit if a single content-
type is used to for all kinds of reports.
This document is part of a four document set describing the delivery
status report service. This collection includes the Simple Mail
Transfer Protocol (SMTP) extensions to request delivery status
reports, a MIME content for the reporting of delivery reports, an
enumeration of extended status codes, and a multipart container for
the delivery report, the original message, and a human-friendly
summary of the failure.
