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 \fBmaster.cf\fR file (either +\fBbounce\fR, \fBdefer\fR or \fBtrace\fR). +This program expects to be run from the \fBmaster\fR(8) process +manager. + +The \fBbounce\fR(8) daemon processes two types of service requests: +.IP \(bu +Append a recipient (non\-)delivery status record to a per\-message +log file. +.IP \(bu +Enqueue a delivery status notification message, with a copy +of a per\-message log file and of the corresponding message. +When the delivery status notification message is +enqueued successfully, the per\-message log file is deleted. +.PP +The software does a best notification effort. A non\-delivery +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. +.SH "STANDARDS" +.na +.nf +RFC 822 (ARPA Internet Text Messages) +RFC 2045 (Format of Internet Message Bodies) +RFC 2822 (Internet Message Format) +RFC 3462 (Delivery Status Notifications) +RFC 3464 (Delivery Status Notifications) +RFC 3834 (Auto\-Submitted: message header) +RFC 5322 (Internet Message Format) +RFC 6531 (Internationalized SMTP) +RFC 6532 (Internationalized Message Format) +RFC 6533 (Internationalized Delivery Status Notifications) +.SH DIAGNOSTICS +.ad +.fi +Problems and transactions are logged to \fBsyslogd\fR(8) +or \fBpostlogd\fR(8). +.SH "CONFIGURATION PARAMETERS" +.na +.nf +.ad +.fi +Changes to \fBmain.cf\fR are picked up automatically, as \fBbounce\fR(8) +processes run for only a limited amount of time.
