bounce - Postfix message bounce or defer daemon
SYNOPSISbounce [generic Postfix daemon options]
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
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
STANDARDSRFC 822 (ARPA Internet Text Messages)
RFC 1894 (Delivery Status Notifications)
Problems and transactions are logged to syslogd(8).
The log files use an ad-hoc, unstructured format. This
will have to change in order to easily support standard
delivery status notifications.
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 postfixreload
command after a configuration change.
The recipient of single bounce postmaster notices.
The recipient of double bounce postmaster notices.
The recipient of "delayed mail" postmaster notices.
Limit the amount of original message context that
is sent in a non-delivery notification.
Use this mail system name in the introductory text
at the start of a bounce message.
Notify the postmaster of bounced mail when this
parameter includes the bounce class. For privacy
reasons, the message body is not included.
