Description

   Use the DIRECTORY command to list any messages which you've sent
   but which have not yet been delivered. The optional type argument
   can be used to restrict the listing to certain types of messages
   such as messages sent to the Internet or other TCP/IP connected
   machines such as UNIX workstations, cc:Mail users, FAX machines,
   etc. A complete list of the available types are shown below. You
   can also use the ? key to obtain a listing of the available types
   as shown in the examples below.

   In the directory listing, each message is assigned a message
   identification number, or "message id" for short. The message id
   appears in the leftmost column. These identification numbers can
   be used with the READ, RETURN, and EDIT_FAX commands to identify
   which messages to read, return, or edit.

   It is important to note that when you send a message to more
   than one recipient, the message might split into multiple message
   copies. Consequently, the same message might appear multiple
   times as being queued to different networks (or possibly even for
   the same network). Such would be the case for a message sent both
   to local users and remote users.
