ERROR(8) System Manager's Manual ERROR(8)
error - Postfix error mailer
error [generic Postfix daemon options]
The Postfix error mailer processes message 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. This program expects to be run from the mas-
ter(8) process manager.
The error mailer client forces all recipients to bounce, using the
domain or host information as the reason for non-delivery, updates the
queue file and marks recipients as finished, or it informs the queue
manager that delivery should be tried again at a later time.
Delivery problem reports are sent to the bounce(8) or defer(8) daemon
The error mailer is not security-sensitive. It does not talk to the
network, and can be run chrooted at fixed low privilege.
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.
The following main.cf parameters are especially relevant to this pro-
gram. See the Postfix main.cf file for syntax details and for default
values. Use the postfix reload command after a configuration change.
Postmaster for bounce error notices.
When this parameter includes the bounce class, send mail to the
postmaster with the headers of the bounced mail.
