    1.MAIL> EXIT
        Job 790 entered on queue ATLAS_PRINT

      When you are ready to leave Mail, enter the EXIT command and
      press Return. If AUTO_PURGE is set, Mail deletes any messages
      marked for deletion. In this example, the message that was
      marked for printing enters the default print queue after you
      enter the EXIT command.
