BOUNCE(8) BOUNCE(8) NAME bounce - Postfix message bounce or defer daemon SYNOPSIS bounce [generic Postfix daemon options] DESCRIPTION The bounce(8) 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, defer or trace). This program expects to be run from the master(8) process man- ager. The bounce(8) daemon processes two types of service requests: o Append a recipient (non-)delivery status record to a per-message log file. o Enqueue a bounce message, with a copy of a per-mes- sage log file and of the corresponding message. When the bounce message is enqueued successfully, the per-message log file is deleted. The software does a best notification effort. A non-deliv- ery notification is sent even when the log file or the original message cannot be read. Optionally, a bounce (defer, trace) 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). CONFIGURATION PARAMETERS Changes to main.cf are picked up automatically, as bounce(8) processes run for only a limited amount of time. Use the command "postfix reload" to speed up a change. The text below provides only a parameter summary. See postconf(5) for more details including examples. 2bounce_notice_recipient (postmaster) The recipient of undeliverable mail that cannot be returned to the sender. backwards_bounce_logfile_compatibility (yes) Produce additional bounce(8) logfile records that can be read by Postfix versions before 2.0. bounce_notice_recipient (postmaster) The recipient of postmaster notifications with the message headers of mail that Postfix did not deliver and of SMTP conversation transcripts of mail that Postfix did not receive. bounce_size_limit (50000) The maximal amount of original message text that is sent in a non-delivery notification. config_directory (see 'postconf -d' output) The default location of the Postfix main.cf and master.cf configuration files. daemon_timeout (18000s) How much time a Postfix daemon process may take to handle a request before it is terminated by a built-in watchdog timer. delay_notice_recipient (postmaster) The recipient of postmaster notifications with the message headers of mail that cannot be delivered within $delay_warning_time time units. deliver_lock_attempts (20) The maximal number of attempts to acquire an exclu- sive lock on a mailbox file or bounce(8) logfile. deliver_lock_delay (1s) The time between attempts to acquire an exclusive lock on a mailbox file or bounce(8) logfile. ipc_timeout (3600s) The time limit for sending or receiving information over an internal communication channel. mail_name (Postfix) The mail system name that is displayed in Received: headers, in the SMTP greeting banner, and in bounced mail. max_idle (100s) The maximum amount of time that an idle Postfix daemon process waits for the next service request before exiting. max_use (100) The maximal number of connection requests before a Postfix daemon process terminates. notify_classes (resource, software) The list of error classes that are reported to the postmaster. process_id (read-only) The process ID of a Postfix command or daemon process. process_name (read-only) The process name of a Postfix command or daemon process. queue_directory (see 'postconf -d' output) The location of the Postfix top-level queue direc- tory. syslog_facility (mail) The syslog facility of Postfix logging. syslog_name (postfix) The mail system name that is prepended to the process name in syslog records, so that "smtpd" becomes, for example, "postfix/smtpd".
