    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 postmaster is notified of bounces and of  other  trou-
           ble.
