# 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 $daemon_directory/postfix-files, 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 $daemon_directory/postfix-files, 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 $daemon_directory/postfix-files, 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
# .ad
# .fi
# The description of installation parameters is as follows:
# .IP config_directory
# The directory for Postfix configuration files.
# .IP daemon_directory
# The directory for Postfix daemon programs. This directory
# should not be in the command search path of any users.
# .IP command_directory
# The directory for Postfix administrative commands. This
# directory should be in the command search path of adminstrative users.
# .IP queue_directory
# The directory for Postfix queues.
# .IP data_directory
# The directory for Postfix writable data files (caches, etc.).
# .IP sendmail_path
# The full pathname for the Postfix sendmail command.
# This is the Sendmail-compatible mail posting interface.
# .IP newaliases_path
# The full pathname for the Postfix newaliases command.
# This is the Sendmail-compatible command to build alias databases
# 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
# The owner of the Postfix queue. Its numerical user ID and group ID
# 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.
# .IP sample_directory
# The directory for the Postfix sample configuration files.
# This feature is obsolete as of Postfix 2.1.
# .IP readme_directory
# The directory for the Postfix README files.

BTW: Check your $ALIASES file and be sure to set up aliases
that send mail for root and postmaster to a real person, then
run $NEWALIASES_PATH.
