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 # .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. # .IP shlib_directory # The directory for the Postfix shared-library files, and for # the Postfix dabatase plugin files with a relative pathname # in the file dynamicmaps.cf. # .IP meta_directory # The directory for non-executable files that are shared # among multiple Postfix instances, such as postfix-files, # dynamicmaps.cf, as well as the multi-instance template files # main.cf.proto and master.cf.proto. # SEE ALSO # postfix-install(1) Postfix primary installation script. # FILES # $config_directory/main.cf, Postfix installation parameters. # $meta_directory/postfix-files, installation control file. # $meta_directory/postfix-files.d/, optional control files. # $config_directory/install.cf, obsolete configuration file. # LICENSE # .ad # .fi # The Secure Mailer license must be distributed with this software. # AUTHOR(S) # Wietse Venema # IBM T.J.
