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  ad-
       dress,  the reason for non-delivery (specified as the next-hop destina-
       tion), 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, 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 ser-
       vice 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) or postlogd(8).

       Depending on the	setting	of the notify_classes parameter, the  postmas-
       ter is notified of bounces and of other trouble.

       Changes	to  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.
