/* NAME
/* bounce 8
/* SUMMARY
/* Postfix delivery status reports
/* SYNOPSIS
/* \fBbounce\fR [generic Postfix daemon options]
/* DESCRIPTION
/* The \fBbounce\fR(8) daemon maintains per-message log files with
/* 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 \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.
/* STANDARDS
/* RFC 822 (ARPA Internet Text Messages)
/* RFC 2045 (Format of Internet Message Bodies)
/* RFC 2822 (Internet Message Format)
/* RFC 3462 (Delivery Status Notifications)

/* RFC 5322 (Internet Message Format)
/* RFC 6531 (Internationalized SMTP)

/* DIAGNOSTICS
/* Problems and transactions are logged to \fBsyslogd\fR(8).
/* CONFIGURATION PARAMETERS
/* .ad

/* of mail that cannot be delivered within $delay_warning_time time
/* units.

/* mailbox file or \fBbounce\fR(8) logfile.
/* .IP "\fBdeliver_lock_delay (1s)\fR"
