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:

       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 themselves, 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  notifica-
       tions.

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.

	      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.
