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 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 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.
