NAME

       bounce - Postfix delivery status reports

SYNOPSIS

       bounce [generic Postfix daemon options]

DESCRIPTION

       The  bounce(8)  daemon maintains per-message log files with delivery status 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 master.cf file (either bounce, defer or trace).  This program expects to be run from
       the master(8) process manager.

       The bounce(8) daemon processes two types of service requests:

       •      Append a recipient (non-)delivery status record to a per-message log file.

       •      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 notification 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.

       Changes  to  main.cf are picked up automatically, as bounce(8) processes run for only a limited amount of
       time. Use the command "postfix reload" to speed up a change.
