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. +# SEE ALSO +# postfix(1) Postfix control program +# postfix-wrapper(5) multi-instance manager API +# postmulti(1) full-blown multi-instance manager +# LICENSE +# .ad +# .fi +# The Secure Mailer license must be distributed with this software. +# AUTHOR(S) +# Wietse Venema +# IBM T.J.
