Each request specifies a queue file, a sender 18 address, the reason for non-delivery (specified as the next-hop desti- 19 nation), and recipient information. The reason may be prefixed with an 20 <a href="https://tools.ietf.org/html/rfc3463">RFC 3463</a>-compatible detail code; if none is specified a default 4.0.0 21 or 5.0.0 code is used instead. This program expects to be run from the 22 <a href="master.8.html"><b>master</b>(8)</a> process manager. 23 24 Depending on the service name in <a href="master.5.html">master.cf</a>, <b>error</b> or <b>retry</b>, the server 25 bounces or defers all recipients in the delivery request using the 26 "next-hop" information as the reason for non-delivery. The <b>retry</b> ser- 27 vice name is supported as of Postfix 2.4. 28 29 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> 30 daemon as appropriate. 31 32<b>SECURITY</b> 33 The <a href="error.8.html"><b>error</b>(8)</a> mailer is not security-sensitive. It does not talk to the 34 network, and can be run chrooted at fixed low privilege. 35 36<b>STANDARDS</b> 37 <a href="https://tools.ietf.org/html/rfc3463">RFC 3463</a> (Enhanced Status Codes) 38 39<b>DIAGNOSTICS</b> 40 Problems and transactions are logged to <b>syslogd</b>(8) or <a href="postlogd.8.html"><b>postlogd</b>(8)</a>. 41 42 Depending on the setting of the <b><a href="postconf.5.html#notify_classes">notify_classes</a></b> parameter, the postmas- 43 ter is notified of bounces and of other trouble. 44 45<b>CONFIGURATION PARAMETERS</b> 46 Changes to <a href="postconf.5.html"><b>main.cf</b></a> are picked up automatically as <a href="error.8.html"><b>error</b>(8)</a> processes 47 run for only a limited amount of time. Use the command "<b>postfix reload</b>" 48 to speed up a change. 49 50 The text below provides only a parameter summary.
