Each log file is named after the queue file that it 18 corresponds to, and is kept in a queue subdirectory named after the 19 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>). 20 This program expects to be run from the <a href="master.8.html"><b>master</b>(8)</a> process manager. 21 22 The <a href="bounce.8.html"><b>bounce</b>(8)</a> daemon processes two types of service requests: 23 24 <b>o</b> Append a recipient (non-)delivery status record to a per-message 25 log file. 26 27 <b>o</b> Enqueue a delivery status notification message, with a copy of a 28 per-message log file and of the corresponding message. When the 29 delivery status notification message is enqueued successfully, 30 the per-message log file is deleted. 31 32 The software does a best notification effort. A non-delivery notifica- 33 tion is sent even when the log file or the original message cannot be 34 read. 35 36 Optionally, a bounce (defer, trace) client can request that the 37 per-message log file be deleted when the requested operation fails. 38 This is used by clients that cannot retry transactions by themselves, 39 and that depend on retry logic in their own client. 40 41<b>STANDARDS</b> 42 <a href="http://tools.ietf.org/html/rfc822">RFC 822</a> (ARPA Internet Text Messages) 43 <a href="http://tools.ietf.org/html/rfc2045">RFC 2045</a> (Format of Internet Message Bodies) 44 <a href="http://tools.ietf.org/html/rfc2822">RFC 2822</a> (Internet Message Format) 45 <a href="http://tools.ietf.org/html/rfc3462">RFC 3462</a> (Delivery Status Notifications) 46 <a href="http://tools.ietf.org/html/rfc3464">RFC 3464</a> (Delivery Status Notifications) 47 <a href="http://tools.ietf.org/html/rfc3834">RFC 3834</a> (Auto-Submitted: message header) 48 <a href="http://tools.ietf.org/html/rfc5322">RFC 5322</a> (Internet Message Format) 49 <a href="http://tools.ietf.org/html/rfc6531">RFC 6531</a> (Internationalized SMTP) 50 <a href="http://tools.ietf.org/html/rfc6532">RFC 6532</a> (Internationalized Message Format) 51 <a href="http://tools.ietf.org/html/rfc6533">RFC 6533</a> (Internationalized Delivery Status Notifications) 52 53<b>DIAGNOSTICS</b> 54 Problems and transactions are logged to <b>syslogd</b>(8) or <a href="postlogd.8.html"><b>postlogd</b>(8)</a>. 55 56<b>CONFIGURATION PARAMETERS</b> 57 Changes to <a href="postconf.5.html"><b>main.cf</b></a> are picked up automatically, as <a href="bounce.8.html"><b>bounce</b>(8)</a> processes 58 run for only a limited amount of time.
