<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.
