+# NAME
+#	postfix-wrapper 1
+# SUMMARY
+#	trivial but useful multi-instance manager
+# SYNOPSIS
+#	postfix command
+# DESCRIPTION
+#	Postfix versions 2.6 and later provide support for multiple
+#	Postfix instances. Instances share executable files and
+#	documentation, but have their own directories for configuration,
+#	queue and data files. In many cases different instances
+#	have different myhostname and inet_interfaces settings,
+#	though this is not always necessary.
+#
+#	This command implements a trivial Postfix multi-instance
+#	manager. It simply applies commands such as "postfix start"
+#	to all the applicable Postfix instances.
+# MANAGING MULTIPLE INSTANCES
+# .ad
+# .fi
+#	To hook the postfix-wrapper multi-instance manager into
+#	Postfix, see the POSTFIX-WRAPPER INITIALIZATION section
+#	below.  To create a new Postfix instance, see the CREATING
+#	A NEW POSTFIX INSTANCE section below.
+#
+#	To start, stop, get status, etc., with multiple Postfix
+#	instances, use:
+#
+# .nf
+#	    # postfix command
+# .fi
+#
+#	For example, to find out what Postfix instances are configured:
+#
+# .nf
+#	    # postfix status
+# .fi
+#
+#	The postfix(1) command invokes the postfix-wrapper command.
+#	This in turn applies the postfix(1) command to the default
+#	Postfix instance, and to each instance specified with the
+#	default main.cf file's multi_instance_directories parameter
+#	value.
+#
+#	The postfix-wrapper command will start, stop, reload, etc.,
+#	only Postfix instances that have "multi_instance_enable =
+#	yes" in their main.cf files.  When an instance is disabled,
+#	postfix-wrapper replaces "start" commands by "check" so
+#	that problems will still be reported.
+#
+#	The startup order is taken from the multi_instance_directories
+#	parameter; the default instance is prepended to the list.
+#	The startup order is used for all postfix(1) commands,
+#	except for commands that stop Postfix instances. In those
+#	cases the order is reversed.
+# MANAGING INDIVIDUAL INSTANCES
+# .ad
+# .fi
+#	To manage an individual Postfix instance, use:
+#
+# .nf
+#	    # postfix -c /path/to/config_directory command
+# .fi
+#
+#	This is also needed to manage the default Postfix instance,
+#	after you turn on multi-instance support.
+#
+#	To use the Postfix sendmail command with a non-default
+#	Postfix instance, use:
+#
+# .nf
+#	    # sendmail -C /path/to/config_directory ...
+# .fi
+#
+#	Note 1: that's capital C, not lower-case c.
+#
+#	Note 2: only the default Postfix instance will check or
+#	update the shared Postfix files, including the executable
+#	files and documentation.
+# POSTFIX-WRAPPER INITIALIZATION
+# .ad
+# .fi
+#	To hook this program into Postfix, execute the command
+#	shown below.
+#
+#	This command should be entered as one line.
+#
+#	In the example, replace /etc/postfix with the default Postfix
+#	configuration directory, and replace /usr/libexec/postfix
+#	with the daemon directory pathname of the default Postfix
+#	instance.
+#
+# .nf
+#	    # postconf -c /etc/postfix -e
+#		"multi_instance_enable=yes"
+#		"multi_instance_wrapper=/usr/libexec/postfix/postfix-wrapper"
+# .fi
+# CREATING A NEW POSTFIX INSTANCE
+# .ad
+# .fi
+#	To create a Postfix instance called "postfix-test", start
+#	with generic main.cf and master.cf files and customize the
+#	locations of the queue and data directories with the commands
+#	shown below.  The last command updates main.cf and creates
+#	any directories that Postfix will need.
+#
+#	Each command below should be entered as one line.
+#
+#	In the example, replace /etc/postfix with the default Postfix
+#	configuration directory, and replace /usr/libexec/postfix
+#	with the daemon directory pathname of the default Postfix
+#	instance.
+#
+# .nf
+#	    # mkdir /etc/postfix-test
+#	    # cp /usr/libexec/postfix/main.cf /etc/postfix-test
+#	    # cp /usr/libexec/postfix/master.cf /etc/postfix-test
+#	    # postconf -c /etc/postfix-test -e 
+#		"multi_instance_name=postfix-test"
+#	    # postfix -c /etc/postfix post-install
+#		"config_directory=/etc/postfix-test"
+#		"queue_directory=/var/spool/postfix-test"
+#		"data_directory=/var/lib/postfix-test"
+#		create-missing
+# .fi
+#
+#	Register this Postfix instance with the default instance.
+#	This command should be entered as one line.
+#
+# .nf
+#	    # postconf -e "multi_instance_directories=`postconf
+#		-h multi_instance_directories` /etc/postfix-test"
+# .fi
+#
+#	Edit the myhostname and inet_interfaces main.cf parameters,
+#	so that they will not conflict with the default Postfix
+#	instance, and change whatever else needs to be changed.
+#
+#	Test the instance with:
+#
+# .nf
+#	    # postfix -c /etc/postfix-test start
+#	    # postfix -c /etc/postfix-test status
+#	    [ other tests ... ]
+# .fi
+#
+#	When everything is working satisfactorily, enable start/stop/etc.
+#	by the multi-instance manager:
+#
+# .nf
+#	    # postconf -c /etc/postfix-test -e multi_instance_enable=yes
+# DIAGNOSTICS
+# .ad
+# .fi
+#	When an operation fails, the affected Postfix instance logs
+#	a message, and the multi-instance manager skips to the next
+#	instance.
+# BUGS
+#	Support for the multi_instance_group feature is not implemented.
