Ubuntu Manpage: bounce - Postfix delivery status reports

Provided by: postfix_3.7.4-2build1_amd64

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.
