BOUNCE(8)                                               BOUNCE(8)

NAME
       bounce - Postfix message bounce or defer daemon

SYNOPSIS
       bounce [generic Postfix daemon options]

DESCRIPTION
       The  bounce  daemon  maintains  per-message log files with
       non-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 or defer).  This program
       expects to be run from the master(8) process manager.

       The bounce daemon processes two types of service requests:

       o      Append  a  recipient status record to a per-message
              log file.

       o      Post a bounce message, with a copy of  a  log  file
              and  of  the corresponding message. When the bounce
              is posted successfully, the log file is deleted.

       The software does a best effort to notify the sender  that
       there  was a problem. A notification is sent even when the
       log file or original message cannot be read.

       Optionally, a 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 them-
       selves,  and  that  depend  on  retry  logic  in their own
       client.

STANDARDS
       RFC 822 (ARPA Internet Text Messages)
       RFC 1894 (Delivery Status Notifications)

DIAGNOSTICS
       Problems and transactions are logged to syslogd(8).

BUGS
       The log files use an  ad-hoc,  unstructured  format.  This
       will  have  to  change in order to easily support standard
       delivery status notifications.

CONFIGURATION PARAMETERS
       The following main.cf parameters are  especially  relevant
       to  this  program. See the Postfix main.cf file for syntax
       details and for default values.  Use  the  postfix  reload
       command after a configuration change.

       bounce_notice_recipient
              The  recipient of single bounce postmaster notices.

       2bounce_notice_recipient
              The recipient of double bounce postmaster  notices.

       delay_notice_recipient
              The recipient of "delayed mail" postmaster notices.

       bounce_size_limit
              Limit the amount of original message  context  that
              is sent in a non-delivery notification.

       mail_name
              Use  this mail system name in the introductory text
              at the start of a bounce message.

       notify_classes
              Notify the postmaster of  bounced  mail  when  this
              parameter  includes  the  bounce class. For privacy
              reasons, the message body is not included.
