+# 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.
