        RFC 1524:

        Title:      A User Agent Configuration Mechanism
                    For Multimedia Mail Format Information

This memo suggests a file format to be used to inform multiple mail
reading user agent programs about the locally-installed facilities for
handling mail in various formats.  The mechanism is explicitly
designed to work with mail systems based Internet mail as defined by
RFC's 821 (STD 10), 822 (STD 11), 934, 1049 (STD 11), 1113, and the
Multipurpose Internet Mail Extensions, known as MIME.  However, with
some extensions it could probably be made to work for X.400-based mail
systems as well.  The format and mechanism are proposed in a manner
that is generally operating-system independent.  However, certain
implementation details will inevitably reflect operating system
differences, some of which will have to be handled in a uniform manner
for each operating system.  This memo makes such situations explicit,
and, in an appendix, suggests a standard behavior under the UNIX
operating system.

This memo provides information for the Internet community.  It does
