ERROR(8) System Manager's Manual ERROR(8)

error - Postfix error/retry mail delivery agent

error [generic Postfix daemon options]

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.



The error(8) mailer is not security-sensitive. It does not
    talk to the network, and can be run chrooted at fixed low privilege.








RFC 3463 (Enhanced Status Codes)








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.










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.
