IMAP4 has two commands for listing mailboxes: LIST and LSUB.  As we
have added extensions, such as Mailbox Referrals, that have required
specialized lists 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.  [STANDARDS TRACK]
