Commands

   Note that while there is a fair amount of commonality amongst
   the commands accepted by many of the different mail servers,
   differences also exist. Do not expect PMDF mail server commands
   to work with other mail servers and do not expect other mail
   server commands to work with PMDF mail servers. When you are
   unsure of what sort of mail server you are dealing with, the
   first order of business should be obtaining help information for
   that server. Often this can be done by sending the command HELP
   to the server.
