Postfix error 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, a domain or host name that is treated as the reason for
non-delivery, and recipient information.
The reason may be prefixed with an RFC 3463-compatible detail code.
This program expects to be run from the
master(8) process
manager.
The error(8) delivery agent bounces all recipients in the delivery
request using the "next-hop"
domain or host information as the reason for non-delivery, updates
the queue file and marks recipients as finished or informs the
queue manager that delivery should be tried again at a later time.
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.
