- This command can return three possible results. An ERROR code may be returned
-if no user is currently logged in or if something else went wrong. Otherwise,
-LISTING_FOLLOWS will be returned, and the listing will consist of zero or
-more message numbers, one per line. The listing ends, as always, with the
-string "000" alone on a line by itself. The listed message numbers can be used
-to request messages from the system. If "search mode" is being used, the
-server will return START_CHAT_MODE, and the client is expected to transmit
-the search criteria, and then read the message list.
