+<b>NAME</b>
+ bounce - Postfix delivery status reports
+
+<b>SYNOPSIS</b>
+ <b>bounce</b> [generic Postfix daemon options]
+
+<b>DESCRIPTION</b>
+ The <a href="bounce.8.html"><b>bounce</b>(8)</a> daemon maintains per-message log files with delivery sta-
+ tus information. Each log file is named after the queue file that it
+ corresponds to, and is kept in a queue subdirectory named after the
+ service name in the <a href="master.5.html"><b>master.cf</b></a> file (either <b>bounce</b>, <b>defer</b> or <b>trace</b>).
+ This program expects to be run from the <a href="master.8.html"><b>master</b>(8)</a> process manager.
+
+ The <a href="bounce.8.html"><b>bounce</b>(8)</a> daemon processes two types of service requests:
+
+ <b>o</b> Append a recipient (non-)delivery status record to a per-message
+ log file.
+
+ <b>o</b> Enqueue a delivery status notification message, with a copy of a
+ per-message log file and of the corresponding message. When the
+ delivery status notification message is enqueued successfully,
+ the per-message log file is deleted.
+
+ The software does a best notification effort. A non-delivery notifica-
+ tion is sent even when the log file or the original message cannot be
+ read.
+
+ Optionally, a bounce (defer, trace) client can request that the
+ per-message log file be deleted when the requested operation fails.
+ This is used by clients that cannot retry transactions by themselves,
+ and that depend on retry logic in their own client.
