ERROR(8)                                       System Manager's Manual                                       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 speciā€
       fied 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
       supported 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
       trouble.

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 postconf(5) for more details including examples.

       2bounce_notice_recipient (postmaster)

       bounce_notice_recipient (postmaster)

              and of SMTP conversation transcripts of mail that Postfix did not receive.

       config_directory (see 'postconf -d' output)
              The default location of the Postfix main.cf and master.cf configuration files.

       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)

       notify_classes (resource, software)
              The list of error classes that are reported to the postmaster.

       process_id (read-only)

       process_name (read-only)

       syslog_facility (mail)
              The syslog facility of Postfix logging.

       syslog_name (see 'postconf -d' output)
              The mail system name that is prepended to the process name in syslog records, so that "smtpd"  becomes,
              for example, "postfix/smtpd".
