bouncesaying - perhaps bounce each incoming message

          in .qmail:  |bouncesaying error [ program [ arg ... ] ]

          bouncesaying feeds each new mail message to program with the
          given arguments.  If program exits 0, bouncesaying prints
          error and bounces the message.

          If program exits 111, bouncesaying exits 111, so delivery
          will be retried later.

          If program exits anything else (or does not exist),
          bouncesaying exits 0, so the rest of .qmail will be
          processed as usual.

          Note that it is not safe for program to fork a child that
          reads the message in the background.

          If program is not supplied, bouncesaying always bounces the

             |bouncesaying 'This address no longer accepts mail.'

          WARNING: If you create a .qmail file to enable bouncesaying,
          make sure to also add a line specifying delivery to your
          normal mailbox.
