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:

· 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 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)
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 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.
