BOUNCE(8) BOUNCE(8) Page 1 of 2 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: o o 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 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 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. 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 http://www.porcupine.org/postfix-mirror/bounce.8.html 6/26/01
Limit the amount of original message context that is sent in a non-delivery notification. Page 2 of 2 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.
