Abstract

   This memo requests that the application/mbox media type be authorized
   for allocation by the IESG, according to the terms specified in RFC
   2048.  This memo also defines a default format for the mbox database,
   which must be supported by all conformant implementations.

1.  Background and Overview

   UNIX-like operating systems have historically made widespread use of
   "mbox" database files for a variety of local email purposes.  In the
   common case, mbox files store linear sequences of one or more
   electronic mail messages, with local email clients treating the
   database as a logical folder of email messages.  mbox databases are
   also used by a variety of other messaging tools, such as mailing list
   management programs, archiving and filtering utilities, messaging
   servers, and other related applications.  In recent years, mbox
   databases have also become common on a large number of non-UNIX
   computing platforms, for similar kinds of purposes.

   The increased pervasiveness of these files has led to an increased
   demand for a standardized, network-wide interchange of these files as
   discrete database objects.  In turn, this dictates a need for a
   general media type definition for mbox files, which is the subject
   and purpose of this memo.

2.  About the mbox Database

   The mbox database format is not documented in an authoritative
   specification, but instead exists as a well-known output format that
   is anecdotally documented, or which is only authoritatively
   documented for a specific platform or tool.

   mbox databases typically contain a linear sequence of electronic mail
   messages.  Each message begins with a separator line that identifies
   the message sender, and also identifies the date and time at which
   the message was received by the final recipient (either the last-hop
   system in the transfer path, or the system which serves as the
   recipient's mailstore).  Each message is typically terminated by an
   empty line.  The end of the database is usually recognized by either
   the absence of any additional data, or by the presence of an expli...
