+/*++
+/* NAME
+/* flush 8
+/* SUMMARY
+/* Postfix fast flush server
+/* SYNOPSIS
+/* \fBflush\fR [generic Postfix daemon options]
+/* DESCRIPTION
+/* The flush server maintains a record of deferred mail by destination.
+/* This information is used to improve the performance of the SMTP
+/* \fBETRN\fR request, and of its command-line equivalent,
+/* \fBsendmail -qR\fR.
+/* This program expects to be run from the \fBmaster\fR(8) process
+/* manager.
+/*
+/* The record is implemented as a per-destination logfile with
+/* as contents the queue IDs of deferred mail. A logfile is
+/* append-only, and is truncated when delivery is requested
+/* for the corresponding destination. A destination is the
+/* part on the right-hand side of the right-most \fB@\fR in
+/* an email address.
+/*
+/* Per-destination logfiles of deferred mail are maintained only for
+/* eligible destinations. The list of eligible destinations is
+/* specified with the \fBfast_flush_domains\fR configuration parameter,
+/* which defaults to \fB$relay_domains\fR.
+/*
+/* This server implements the following requests:
+/* .IP "\fBFLUSH_REQ_ADD\fI sitename queue_id\fR"
+/* Inform the fast flush server that the specified message is queued for
+/* \fIsitename\fR. Depending on logging policy, the fast flush server
+/* stores or ignores the information.
+/* .IP "\fBFLUSH_REQ_SEND\fI sitename\fR"
+/* Request delivery of mail that is queued for \fIsitename\fR.
+/* If the destination is eligible for a fast flush logfile,
+/* this request triggers delivery of messages listed in that
+/* destination's logfile, and the logfile is truncated to zero length;
+/* if mail is undeliverable it will be added back to the logfile.
+/* .sp
+/* If the destination is not eligible for a fast flush logfile,
+/* this request triggers delivery of all queued mail.
+/* .IP \fBTRIGGER_REQ_WAKEUP\fR
+/* This wakeup request from the master is an alternative way to
+/* request \fBFLUSH_REQ_REFRESH\fR.
+/* .IP "\fBFLUSH_REQ_REFRESH\fR (completes in the background)"
+/* Refresh non-empty per-destination logfiles that were not read in
+/* \fBfast_flush_refresh_time\fR hours, by simulating
+/* send requests (see above) for the corresponding destinations.
+/* .sp
+/* Delete empty per-destination logfiles that were not updated in
+/* \fBfast_flush_purge_time\fR days.
+/* .IP "\fBFLUSH_REQ_PURGE\fR (completes in the background)"
+/* Refresh all non-empty per-destination logfiles, by simulating
+/* send requests (see above) for the corresponding destinations.
+/* This can be incredibly expensive when logging is enabled for
+/* many destinations, and is not recommended.
+/* .sp
+/* Delete empty per-destination logfiles that were not updated in
+/* \fBfast_flush_purge_time\fR days.
+/* .PP
+/* The server response is one of:
+/* .IP \fBFLUSH_STAT_OK\fR
+/* The request completed normally.
+/* .IP \fBFLUSH_STAT_BAD\fR
+/* The flush server rejected the request (bad request name, bad
+/* request parameter value).
+/* .IP \fBFLUSH_STAT_FAIL\fR
+/* The request failed.
+/* SECURITY
+/* .ad
+/* .fi
+/* The fast flush server is not security-sensitive. It does not
+/* talk to the network, and it does not talk to local users.
+/* The fast flush server can run chrooted at fixed low privilege.
+/* DIAGNOSTICS
+/* Problems and transactions are logged to \fBsyslogd\fR(8).
+/* BUGS
+/* Fast flush logfiles are truncated only after a \fBFLUSH_REQ_SEND\fR
+/* request, not when mail is actually delivered, and therefore can
+/* accumulate outdated or redundant data. In order to maintain sanity,
+/* \fBFLUSH_REQ_REFRESH\fR must be executed periodically. This can
+/* be automated with a suitable wakeup timer setting in the
+/* \fBmaster.cf\fR configuration file.
+/*
+/* Upon receipt of a request to deliver all mail for an eligible
+/* destination, the \fBflush\fR server requests delivery of all messages
+/* that are listed in that destination's logfile, regardless of the
+/* recipients of those messages. This is not an issue for mail
+/* that is sent to a \fBrelay_domains\fR destination because
+/* such mail typically only has recipients in one domain.
+/* FILES
+/* /var/spool/postfix/flush, location of "fast flush" logfiles.
+/* CONFIGURATION PARAMETERS
+/* .ad
+/* .fi
+/* See the Postfix \fBmain.cf\fR file for syntax details and for
+/* default values. Use the \fBpostfix reload\fR command after a
+/* configuration change.
+/* .IP \fBfast_flush_domains\fR
+/* What destinations can have a "fast flush" logfile. By default,
+/* this is set to \fB$relay_domains\fR.
+/* .IP \fBfast_flush_refresh_time\fR
+/* Refresh a non-empty "fast flush" logfile that was not read in
+/* this amount of time (default time unit: hours), by simulating
+/* a send request for the corresponding destination.
+/* .IP \fBfast_flush_purge_time\fR
+/* Remove an empty "fast flush" logfile that was not updated in
+/* this amount of time (default time unit: days).
