+DISCARD(8) DISCARD(8)
+
+<b>NAME</b>
+ discard - Postfix discard mail delivery agent
+
+<b>SYNOPSIS</b>
+ <b>discard</b> [generic Postfix daemon options]
+
+<b>DESCRIPTION</b>
+ The Postfix <a href="discard.8.html"><b>discard</b>(8)</a> delivery agent processes delivery requests from
+ the queue manager. Each request specifies a queue file, a sender
+ address, a next-hop destination that is treated as the reason for dis-
+ carding the mail, and recipient information. The reason may be pre-
+ fixed with an <a href="http://tools.ietf.org/html/rfc3463">RFC 3463</a>-compatible detail code. This program expects to
+ be run from the <a href="master.8.html"><b>master</b>(8)</a> process manager.
+
+ The <a href="discard.8.html"><b>discard</b>(8)</a> delivery agent pretends to deliver all recipients in the
+ delivery request, logs the "next-hop" destination as the reason for
+ discarding the mail, updates the queue file, and either marks recipi-
+ ents as finished or informs the queue manager that delivery should be
+ tried again at a later time.
+
+ Delivery status reports are sent to the <a href="trace.8.html"><b>trace</b>(8)</a> daemon as appropriate.
+
+<b>SECURITY</b>
+ The <a href="discard.8.html"><b>discard</b>(8)</a> mailer is not security-sensitive. It does not talk to
+ the network, and can be run chrooted at fixed low privilege.
+
+<b>STANDARDS</b>
+ <a href="http://tools.ietf.org/html/rfc3463">RFC 3463</a> (Enhanced Status Codes)
+
+<b>DIAGNOSTICS</b>
+ Problems and transactions are logged to <b>syslogd</b>(8) or <a href="postlogd.8.html"><b>postlogd</b>(8)</a>.
+
+ Depending on the setting of the <b><a href="postconf.5.html#notify_classes">notify_classes</a></b> parameter, the postmas-
+ ter is notified of bounces and of other trouble.
+
+<b>CONFIGURATION PARAMETERS</b>
+ Changes to <a href="postconf.5.html"><b>main.cf</b></a> are picked up automatically as <a href="discard.8.html"><b>discard</b>(8)</a> processes
+ run for only a limited amount of time. Use the command "<b>postfix reload</b>"
+ to speed up a change.
