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.
