ERROR(8)                                                              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  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
       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  postmas-
       ter is notified of bounces and of other trouble.
