ERROR(8postfix) ERROR(8postfix)
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 desti-
nation), 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 ser-
vice 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 postmas-
ter 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.
