ERROR(8) System Manager's Manual ERROR(8) NAME
error - Postfix error mailer SYNOPSIS
error [generic Postfix daemon options] DESCRIPTION
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 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 as appropriate. SECURITY
The error mailer is not security-sensitive. It does not talk to the network, and can be run chrooted at fixed low privilege. STANDARDS
None. 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. BUGS
CONFIGURATION PARAMETERS
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. Miscellaneous bounce_notice_recipient Postmaster for bounce error notices. notify_classes When this parameter includes the bounce class, send mail to the postmaster with with the headers of the bounced mail.

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 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. 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. 2bounce_notice_recipient (postmaster) The recipient of undeliverable mail that cannot be returned to the sender. bounce_notice_recipient (postmaster) The recipient of postmaster notifications with the message headers of mail that Postfix did not deliver and of SMTP conversation transcripts of mail that Postfix did not receive. config_directory (see 'postconf -d' output) The default location of the Postfix main.cf and master.cf configuration files. daemon_timeout(18000s) How much time a Postfix daemon process may take to handle a request before it is terminated by a built-in watchdog timer. delay_logging_resolution_limit(2) The maximal number of digits after the decimal point when logging sub-second delay values. double_bounce_sender (double-bounce) The sender address of postmaster notifications that are generated by the mail system. ipc_timeout(3600s) The time limit for sending or receiving information over an internal communication channel. max_idle(100s) The maximum amount of time that an idle Postfix daemon process waits for an incoming connection before terminating voluntarily. max_use(100) The maximal number of incoming connections that a Postfix daemon process will service before terminating voluntarily. notify_classes (resource, software) The list of error classes that are reported to the postmaster. process_id (read-only) The process ID of a Postfix command or daemon process. process_name (read-only) The process name of a Postfix command or daemon process. queue_directory (see 'postconf -d' output) The location of the Postfix top-level queue directory. syslog_facility (mail) The syslog facility of Postfix logging. syslog_name (see 'postconf -d' output) The mail system name that is prepended to the process name in syslog records, so that "smtpd" becomes, for example, "postfix/smtpd".
