     The list command prints a list of the messages in the current
     mailbox (or "area").  For each message, the list contains the
     subject header line, the time and date it was created, who it
     is from, how many bytes long it is, and whether or not it has
     been read.

     L by itself will display the headers for all unread messages,
          if any.
     LA will list all messages, read or unread
     LL will display the last <number> of message headers.
     LM is the same as 'L'
     LB will list all bulletins
     LS xxx will list all messages that have the string 'xxx'
            in the Subject: field
     LT will list all traffic
     L> xxx  will list all messages that have the string 'xxx'
             in the To: address
     L< xxx  will list all messages that have the string 'xxx'
             in the From: address

     You may include an optional "starting_msg_number"  from which
     to begin displaying  the list.  If you specify a starting msg
     number, then  you may also specify an  ending number as well.
     This will limit the display for you in case there are a large
     number of messages in a particular "area" mailbox.
