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 master(8) process manager.
The error mailer client forces all recipients to bounce, using the domain or host informa-
tion as the reason for non-delivery, updates the queue file and marks recipients as fin-
ished, or it informs the queue manager that delivery should be tried again at a later
Delivery problem reports are sent to the bounce(8) or defer(8) daemon as appropriate.
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 postmaster is notified of
bounces and of other trouble.
The following main.cf parameters are especially relevant to this program. 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
with the headers of the bounced mail.
