ERROR(8)                                                              ERROR(8)

       error - Postfix error/retry mail delivery agent

       <b>error</b> [generic Postfix daemon options]

       The  Postfix  <a href="error.8.html"><b>error</b>(8)</a>  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 <a href="">RFC</a>
       <a href="">3463</a>-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 <a href="master.8.html"><b>master</b>(8)</a> process manager.

       Depending on the  service  name  in  <a href="master.5.html"></a>,  <b>error</b>  or
       <b>retry</b>,  the server bounces or defers all recipients in the
       delivery request using the "next-hop" information  as  the
       reason  for  non-delivery.  The <b>retry</b> service name is sup-
       ported as of Postfix 2.4.

       Delivery  status  reports  are  sent  to  the   <a href="bounce.8.html"><b>bounce</b>(8)</a>,
       <a href="defer.8.html"><b>defer</b>(8)</a> or <a href="trace.8.html"><b>trace</b>(8)</a> daemon as appropriate.

       The <a href="error.8.html"><b>error</b>(8)</a> mailer is not security-sensitive. It does not
       talk to the network, and can be run chrooted at fixed  low

       <a href="">RFC 3463</a> (Enhanced Status Codes)

       Problems and transactions are logged to <b>syslogd</b>(8).

       Depending  on the setting of the <b><a href="postconf.5.html#notify_classes">notify_classes</a></b> parameter,
       the postmaster is notified of bounces and of  other  trou-

       Changes to <a href="postconf.5.html"><b></b></a> are picked up automatically as <a href="error.8.html"><b>error</b>(8)</a>
       processes run for only a limited amount of time.  Use  the
       command "<b>postfix reload</b>" to speed up a change.
