   9 <b>NAME</b>
  10        bounce - Postfix delivery status reports
  11
  12 <b>SYNOPSIS</b>
  13        <b>bounce</b> [generic Postfix daemon options]
  14
  15 <b>DESCRIPTION</b>
  16        The  <a href="bounce.8.html"><b>bounce</b>(8)</a> daemon maintains per-message log files with
  17        delivery status information. Each log file is named  after
  18        the  queue  file  that it corresponds to, and is kept in a
  19        queue subdirectory named after the  service  name  in  the
  20        <a href="master.5.html"><b>master.cf</b></a> file (either <b>bounce</b>, <b>defer</b> or <b>trace</b>).  This pro-
  21        gram expects to be run from the <a href="master.8.html"><b>master</b>(8)</a> process manager.
  22
  23        The  <a href="bounce.8.html"><b>bounce</b>(8)</a>  daemon  processes  two  types  of  service
  24        requests:
  25
  26        <b>o</b>      Append a recipient (non-)delivery status record  to
  27               a per-message log file.
  28
  29        <b>o</b>      Enqueue  a  delivery  status  notification message,
  30               with a copy of a per-message log file  and  of  the
  31               corresponding  message.   When  the delivery status
  32               notification message is enqueued successfully,  the
  33               per-message log file is deleted.
  34
  35        The software does a best notification effort. A non-deliv-
  36        ery notification is sent even when the  log  file  or  the
  37        original message cannot be read.
  38
  39        Optionally,  a  bounce  (defer,  trace) client can request
  40        that  the  per-message  log  file  be  deleted  when   the
  41        requested  operation  fails.  This is used by clients that
  42        cannot retry transactions by themselves, and  that  depend
  43        on retry logic in their own client.
