ERROR(8)                                                              ERROR(8)

       error - Postfix error/retry mail delivery agent

       error [generic Postfix daemon options]

       The  Postfix  error(8)  delivery  agent processes delivery
       requests from the queue manager. Each request specifies  a
       queue  file, a sender address, the reason for non-delivery
       (specified as the  next-hop  destination),  and  recipient
       information.   The  reason  may  be  prefixed  with an RFC
       3463-compatible  detail  code;  if  none  is  specified  a
       default 4.0.0 or 5.0.0 code is used instead.  This program
       expects to be run from the master(8) process manager.

       Depending on the  service  name  in,  error  or
       retry,  the server bounces or defers all recipients in the
       delivery request using the "next-hop" information  as  the
       reason  for  non-delivery.  The retry service name is sup-
       ported as of Postfix 2.4.

       Delivery  status  reports  are  sent  to  the   bounce(8),
       defer(8) or trace(8) daemon as appropriate.

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

       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  trou-

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