ERROR(8)                                                              ERROR(8)
NAME
       error - Postfix error/retry mail delivery agent
SYNOPSIS
       error [generic Postfix daemon options]
DESCRIPTION
       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  master.cf,  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.
SECURITY
       The error(8) mailer is not security-sensitive. It does not
       talk to the network, and can be run chrooted at fixed  low
       privilege.
STANDARDS
       RFC 3463 (Enhanced Status Codes)
DIAGNOSTICS
       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-
       ble.
CONFIGURATION PARAMETERS
       Changes to main.cf 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.
       The  text  below  provides  only  a parameter summary. See

       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 generated by the mail system.
       ipc_timeout (3600s)
              The time limit for sending or receiving information
              over an 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 termi-
              nating voluntarily.
       notify_classes (resource, software)
              The list of error classes that are reported to  the
