Title : IMAP4 LIST Command Extensions

IMAP4 has two commands for listing mailboxes: LIST and LSUB. As we
have added extensions that have required specialized lists (see
[MboxRefer] for an example) we have had to expand the number of list
commands, since each extension must add its function to both LIST and
LSUB, and these commands are not, as they are defined, extensible.
If we've needed the extensions to work together, we've had to add a
set of commands to mix the different options, the set increasing in
size with each new extension. This document describes an extension
to the base LIST command that will allow these additions to be done
with mutually compatible options to the LIST command, avoiding the
exponential increase in specialized list commands.

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
