+# SUMMARY
+# Postfix post-installation script
+# SYNOPSIS
+# postfix post-install [name=value] command ...
+# DESCRIPTION
+# The post-install script performs the finishing touch of a Postfix
+# installation, after the executable programs and configuration
+# files are installed. Usage is one of the following:
+# .IP o
+# While installing Postfix from source code on the local machine, the
+# script is run by the postfix-install script to update selected file
+# or directory permissions and to update Postfix configuration files.
+# .IP o
+# While installing Postfix from a pre-built package, the script is run
+# by the package management procedure to set all file or directory
+# permissions and to update Postfix configuration files.
+# .IP o
+# The script can be used to change installation parameter settings such
+# as mail_owner or setgid_group after Postfix is already installed.
+# .IP o
+# The script can be used to upgrade configuration files and to upgrade
+# file/directory permissions of a secondary Postfix instance.
+# .IP o
+# At Postfix start-up time, the script is run from "postfix check" to
+# create missing queue directories.
+# .PP
+# The post-install script is controlled by installation parameters.
+# Specific parameters are described at the end of this document.
+# All installation parameters must be specified ahead of time via
+# one of the methods described below.
+#
+# Arguments
+# .IP create-missing
+# Create missing queue directories with ownerships and permissions
+# according to the contents of $meta_directory/postfix-files
+# and optionally in $meta_directory/postfix-files.d/*, using
+# the mail_owner and setgid_group parameter settings from the
+# command line, process environment or from the installed
+# main.cf file.
+#
+# This is required at Postfix start-up time.
+# .IP set-permissions
+# Set all file/directory ownerships and permissions according to the
+# contents of $meta_directory/postfix-files and optionally
+# in $meta_directory/postfix-files.d/*, using the mail_owner
+# and setgid_group parameter settings from the command line,
+# process environment or from the installed main.cf file.
+# Implies create-missing.
+#
+# This is required when installing Postfix from a pre-built package,
+# or when changing the mail_owner or setgid_group installation parameter
+# settings after Postfix is already installed.
+# .IP upgrade-permissions
+# Update ownership and permission of existing files/directories as
+# specified in $meta_directory/postfix-files and optionally
+# in $meta_directory/postfix-files.d/*, using the mail_owner
+# and setgid_group parameter settings from the command line,
+# process environment or from the installed main.cf file.
+# Implies create-missing.
+#
+# This is required when upgrading an existing Postfix instance.
+# .IP upgrade-configuration
+# Edit the installed main.cf and master.cf files, in order to account
+# for missing services and to fix deprecated parameter settings.
+#
+# This is required when upgrading an existing Postfix instance.
+# .IP upgrade-source
+# Short-hand for: upgrade-permissions upgrade-configuration.
+#
+# This is recommended when upgrading Postfix from source code.
+# .IP upgrade-package
+# Short-hand for: set-permissions upgrade-configuration.
+#
+# This is recommended when upgrading Postfix from a pre-built package.
+# .IP first-install-reminder
+# Remind the user that they still need to configure main.cf and the
+# aliases file, and that newaliases still needs to be run.
+#
+# This is recommended when Postfix is installed for the first time.
+# MULTIPLE POSTFIX INSTANCES
+# .ad
+# .fi
+# Multiple Postfix instances on the same machine can share command and
+# daemon program files but must have separate configuration and queue
+# directories.
+#
+# To create a secondary Postfix installation on the same machine,
+# copy the configuration files from the primary Postfix instance to
+# a secondary configuration directory and execute:
+#
+# postfix post-install config_directory=secondary-config-directory \e
+# .in +4
+# queue_directory=secondary-queue-directory \e
+# .br
+# create-missing
+# .PP
+# This creates secondary Postfix queue directories, sets their access
+# permissions, and saves the specified installation parameters to the
+# secondary main.cf file.
+#
+# Be sure to list the secondary configuration directory in the
+# alternate_config_directories parameter in the primary main.cf file.
+#
+# To upgrade a secondary Postfix installation on the same machine,
+# execute:
+#
+# postfix post-install config_directory=secondary-config-directory \e
+# .in +4
+# upgrade-permissions upgrade-configuration
+# INSTALLATION PARAMETER INPUT METHODS
+# .ad
+# .fi
+# Parameter settings can be specified through a variety of
+# mechanisms. In order of decreasing precedence these are:
+# .IP "command line"
+# Parameter settings can be given as name=value arguments on
+# the post-install command line. These have the highest precedence.
+# Settings that override the installed main.cf file are saved.
+# .IP "process environment"
+# Parameter settings can be given as name=value environment
+# variables.
+# Settings that override the installed main.cf file are saved.
+# .IP "installed configuration files"
+# If a parameter is not specified via the command line or via the
+# process environment, post-install will attempt to extract its
+# value from the already installed Postfix main.cf configuration file.
+# These settings have the lowest precedence.
+# INSTALLATION PARAMETER DESCRIPTION

+# .fi
+# The description of installation parameters is as follows:
+# .IP config_directory

+# for the Postfix local delivery agent.
+# .IP mailq_path
+# The full pathname for the Postfix mailq command.
+# This is the Sendmail-compatible command to list the mail queue.
+# .IP mail_owner

+# must not be used by any other accounts on the system.
+# .IP setgid_group
+# The group for mail submission and for queue management commands.
+# Its numerical group ID must not be used by any other accounts on the
+# system, not even by the mail_owner account.
+# .IP html_directory
+# The directory for the Postfix HTML files.
+# .IP manpage_directory
+# The directory for the Postfix on-line manual pages.
