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.

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.
