       discard - Postfix discard mail delivery agent


       discard [generic Postfix daemon options]


       The  Postfix discard(8) delivery agent processes delivery requests from
       the queue manager. Each  request  specifies  a  queue  file,  a  sender
       address,  a  next-hop  destination  that  is  treated as the reason for
       discarding the mail, and recipient  information.   The  reason  may  be
       prefixed with an RFC 3463-compatible detail code.  This program expects
       to be run from the master(8) process manager.

       The discard(8) delivery agent pretends to deliver all recipients in the
       delivery  request,  logs  the  "next-hop" destination as the reason for
       discarding  the  mail,  updates  the  queue  file,  and  either   marks
       recipients  as  finished  or  informs  the  queue manager that delivery
       should be tried again at a later time.

       Delivery status reports are sent to the trace(8) daemon as appropriate.


       The discard(8) mailer is not security-sensitive. It does  not  talk  to
       the network, and can be run chrooted at fixed low privilege.


       RFC 3463 (Enhanced Status Codes)


       Problems and transactions are logged to syslogd(8).

       Depending   on   the  setting  of  the  notify_classes  parameter,  the
       postmaster is notified of bounces and of other trouble.


       Changes to are picked up automatically as discard(8)  processes
       run for only a limited amount of time. Use the command "postfix reload"
       to speed up a change.

       daemon_timeout (18000s)
              How much time a Postfix daemon process  may  take  to  handle  a
              request before it is terminated by a built-in watchdog timer.

       delay_logging_resolution_limit (2)
              The  maximal  number  of  digits  after  the  decimal point when
              logging sub-second delay values.

       double_bounce_sender (double-bounce)
              The  sender  address  of  postmaster  notifications   that   are

              internal communication channel.

       max_idle (100s)
              The maximum amount of time that an idle Postfix  daemon  process
              waits for an incoming connection before terminating voluntarily.

       max_use (100)
              The maximal number of incoming connections that a Postfix daemon
              process will service before terminating voluntarily.

       process_id (read-only)

       qmgr(8), queue manager
       bounce(8), delivery status reports
       error(8), Postfix error delivery agent
       postconf(5), configuration parameters
