/*
6.1.3.  LOGOUT Command

   Arguments:  none

   Responses:  REQUIRED untagged response: BYE

   Result:     OK - logout completed
               BAD - command unknown or arguments invalid

      The LOGOUT command informs the server that the client is done with
      the connection.  The server MUST send a BYE untagged response
      before the (tagged) OK response, and then close the network
      connection.

   Example:    C: A023 LOGOUT
               S: * BYE IMAP4rev1 Server logging out
               S: A023 OK LOGOUT completed
               (Server and client then close the connection)
