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 pro-
       gram expects to be run from the master(8) process manager.

       The bounce daemon processes two types of service requests:

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

       ·      Post a bounce message, with a copy of a log file and of the cor-
              responding 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 mes-
       sage 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 themselves, and that depend on retry
       logic in their own client.


STANDARDS

       RFC 822 (ARPA Internet Text Messages)
       RFC 1894 (Delivery Status Notifications)
       RFC 2045 (Format of Internet Message Bodies)


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 notifica-
       tions.


CONFIGURATION PARAMETERS

       The following main.cf parameters are especially relevant to  this  pro-
       gram.  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.
