In <b>itera-</b> + <b>tor</b> mode, it executes the same command for multiple Postfix instances. + In <b>life-cycle management</b> mode, it adds or deletes one instance, or + changes the multi-instance status of one instance. + + Each mode of operation has its own command syntax. For this reason, + each mode is documented in separate sections below. + +<b>BACKGROUND</b> + A multi-instance configuration consists of one primary Postfix + instance, and one or more secondary instances whose configuration + directory pathnames are recorded in the primary instance's <a href="postconf.5.html">main.cf</a> + file. Postfix instances share program files and documentation, but have + their own configuration, queue and data directories. + + Currently, only the default Postfix instance can be used as primary + instance in a multi-instance configuration. The <a href="postmulti.1.html"><b>postmulti</b>(1)</a> command + does not currently support a <b>-c</b> option to select an alternative primary + instance, and exits with a fatal error if the <b>MAIL_CONFIG</b> environment + variable is set to a non-default configuration directory. + + See the <a href="MULTI_INSTANCE_README.html">MULTI_INSTANCE_README</a> tutorial for a more detailed discussion + of multi-instance management with <a href="postmulti.1.html"><b>postmulti</b>(1)</a>. + +<b>ITERATOR MODE</b> + In iterator mode, <b>postmulti</b> performs the same operation on all Postfix + instances in turn. + + If multi-instance support is not enabled, the requested command is per- + formed just for the primary instance. + + Iterator mode implements the following command options: + +<b>Instance selection</b> + <b>-a</b> Perform the operation on all instances. This is the default. + + <b>-g</b> <i>group</i> + Perform the operation only for members of the named <i>group</i>. + + <b>-i</b> <i>name</i> + Perform the operation only for the instance with the specified + <i>name</i>. You can specify either the instance name or the absolute + pathname of the instance's configuration directory. Specify "-" + to select the primary Postfix instance. + + <b>-R</b> Reverse the iteration order. This may be appropriate when updat- + ing a multi-instance system, where "sink" instances are started + before "source" instances. + + This option cannot be used with <b>-p</b>. + +<b>List mode</b> + <b>-l</b> List Postfix instances with their instance name, instance group + name, enable/disable status and configuration directory. + +<b>Postfix-wrapper mode</b> + <b>-p</b> <i>postfix-command</i> + Invoke <a href="postfix.1.html"><b>postfix(1)</a></b> to execute <i>postfix-command</i>. This option + implements the <a href="postfix-wrapper.5.html"><b>postfix-wrapper</b>(5)</a> interface. + + <b>o</b> With "start"-like commands, "postfix check" is executed + for instances that are not enabled. The full list of com- + mands is specified with the <a href="postconf.5.html#postmulti_start_commands">postmulti_start_commands</a> + parameter. + + <b>o</b> With "stop"-like commands, the iteration order is + reversed, and disabled instances are skipped. The full + list of commands is specified with the <a href="postconf.5.html#postmulti_stop_commands">post</a>- + <a href="postconf.5.html#postmulti_stop_commands">multi_stop_commands</a> parameter. + + <b>o</b> With "reload" and other commands that require a started + instance, disabled instances are skipped. The full list + of commands is specified with the <a href="postconf.5.html#postmulti_control_commands">postmulti_control_com</a>- + <a href="postconf.5.html#postmulti_control_commands">mands</a> parameter. + + <b>o</b> With "status" and other commands that don't require a + started instance, the command is executed for all + instances. + + The <b>-p</b> option can also be used interactively to start/stop/etc. + a named instance or instance group. For example, to start just + the instances in the group "msa", invoke <a href="postmulti.1.html"><b>postmulti</b>(1)</a> as fol- + lows: + + # postmulti -g msa -p start + +<b>Command mode</b> + <b>-x</b> <i>unix-command</i> + Execute the specified <i>unix-command</i> for all Postfix instances. + The command runs with appropriate environment settings for + MAIL_CONFIG, <a href="postconf.5.html#command_directory">command_directory</a>, <a href="postconf.5.html#daemon_directory">daemon_directory</a>, <a href="postconf.5.html#config_directory">config_direc</a>- + <a href="postconf.5.html#config_directory">tory</a>, <a href="postconf.5.html#queue_directory">queue_directory</a>, <a href="postconf.5.html#data_directory">data_directory</a>, <a href="postconf.5.html#multi_instance_name">multi_instance_name</a>, + <a href="postconf.5.html#multi_instance_group">multi_instance_group</a> and <a href="postconf.5.html#multi_instance_enable">multi_instance_enable</a>. + +<b>Other options</b> + <b>-v</b> Enable verbose logging for debugging purposes. Multiple <b>-v</b> + options make the software increasingly verbose. + +<b>LIFE-CYCLE MANAGEMENT MODE</b> + With the <b>-e</b> option <a href="postmulti.1.html"><b>postmulti</b>(1)</a> can be used to add or delete a Postfix + instance, and to manage the multi-instance status of an existing + instance. + + The following options are implemented: + +<b>Existing instance selection</b> + <b>-a</b> When creating or importing an instance, place the new instance + at the front of the secondary instance list. + + <b>-g</b> <i>group</i> + When creating or importing an instance, place the new instance + before the first secondary instance that is a member of the + specified group. + + <b>-i</b> <i>name</i> + When creating or importing an instance, place the new instance + before the matching secondary instance. + + With other life-cycle operations, apply the operation to the + named existing instance. Specify "-" to select the primary + Postfix instance. + +<b>New or existing instance name assignment</b> + <b>-I</b> <i>name</i> + Assign the specified instance <i>name</i> to an existing instance, + newly-created instance, or imported instance. Instance names + other than "-" (which makes the instance "nameless") must start + with "postfix-". This restriction reduces the likelihood of + name collisions with system files. + + <b>-G</b> <i>group</i> + Assign the specified <i>group</i> name to an existing instance or to a + newly created or imported instance. + +<b>Instance creation/deletion/status change</b> + <b>-e</b> <i>action</i> + "Edit" managed instances. The following actions are supported: + + <b>init</b> This command is required before <a href="postmulti.1.html"><b>postmulti</b>(1)</a> can be used + to manage Postfix instances. The "postmulti -e init" + command updates the primary instance's <a href="postconf.5.html">main.cf</a> file by + setting: + + <a href="postconf.5.html#multi_instance_wrapper">multi_instance_wrapper</a> = + ${<a href="postconf.5.html#command_directory">command_directory</a>}/postmulti -p -- + <a href="postconf.5.html#multi_instance_enable">multi_instance_enable</a> = yes + + You can set these by other means if you prefer. + + <b>create</b> Create a new Postfix instance and add it to the + <a href="postconf.5.html#multi_instance_directories">multi_instance_directories</a> parameter of the primary + instance. The "<b>-I</b> <i>name</i>" option is recommended to give + the instance a short name that is used to construct + default values for the private directories of the new + instance. The "<b>-G</b> <i>group</i>" option may be specified to + assign the instance to a group, otherwise, the new + instance is not a member of any groups. + + The new instance <a href="postconf.5.html">main.cf</a> is the stock <a href="postconf.5.html">main.cf</a> with the + parameters that specify the locations of shared files + cloned from the primary instance. For "nameless" + instances, you should manually adjust "<a href="postconf.5.html#syslog_name">syslog_name</a>" to + yield a unique "logtag" starting with "postfix-" that + will uniquely identify the instance in the mail logs. It + is simpler to assign the instance a short name with the + "<b>-I</b> <i>name</i>" option. + + Optional "name=value" arguments specify the instance <a href="postconf.5.html#config_directory">con</a>- + <a href="postconf.5.html#config_directory">fig_directory</a>, <a href="postconf.5.html#queue_directory">queue_directory</a> and <a href="postconf.5.html#data_directory">data_directory</a>. For + example: + + # postmulti -I postfix-mumble \ + -G mygroup -e create \ + <a href="postconf.5.html#config_directory">config_directory</a>=/my/config/dir \ + <a href="postconf.5.html#queue_directory">queue_directory</a>=/my/queue/dir \ + <a href="postconf.5.html#data_directory">data_directory</a>=/my/data/dir + + If any of these pathnames is not supplied, the program + attempts to generate the pathname by taking the corre- + sponding primary instance pathname, and by replacing the + last pathname component by the value of the <b>-I</b> option. + + If the instance configuration directory already exists, + and contains both a <a href="postconf.5.html">main.cf</a> and <a href="master.5.html">master.cf</a> file, <b>create</b> + will "import" the instance as-is. For existing instances, + <b>create</b> and <b>import</b> are identical. + + <b>import</b> Import an existing instance into the list of instances + managed by the <a href="postmulti.1.html"><b>postmulti</b>(1)</a> multi-instance manager. This + adds the instance to the <a href="postconf.5.html#multi_instance_directories">multi_instance_directories</a> list + of the primary instance. If the "<b>-I</b> <i>name</i>" option is pro- + vided it specifies the new name for the instance and is + used to define a default location for the instance con- + figuration directory (as with <b>create</b> above). The "<b>-G</b> + <i>group</i>" option may be used to assign the instance to a + group. Add a "<b><a href="postconf.5.html#config_directory">config_directory</a>=</b><i>/path</i>" argument to over- + ride a default pathname based on "<b>-I</b> <i>name</i>". + + <b>destroy</b> + Destroy a secondary Postfix instance. To be a candidate + for destruction an instance must be disabled, stopped and + its queue must not contain any messages. Attempts to + destroy the primary Postfix instance trigger a fatal + error, without destroying the instance. + + The instance is removed from the primary instance <a href="postconf.5.html">main.cf</a> + file's <a href="postconf.5.html#alternate_config_directories">alternate_config_directories</a> parameter and its + data, queue and configuration directories are cleaned of + files and directories created by the Postfix system. The + <a href="postconf.5.html">main.cf</a> and <a href="master.5.html">master.cf</a> files are removed from the configu- + ration directory even if they have been modified since + initial creation. Finally, the instance is "deported" + from the list of managed instances. + + If other files are present in instance private directo- + ries, the directories may not be fully removed, a warning + is logged to alert the administrator. It is expected that + an instance built using "fresh" directories via the <b>cre-</b> + <b>ate</b> action will be fully removed by the <b>destroy</b> action + (if first disabled). If the instance configuration and + queue directories are populated with additional files + (access and rewriting tables, chroot jail content, etc.) + the instance directories will not be fully removed. + + The <b>destroy</b> action triggers potentially dangerous file + removal operations. Make sure the instance's data, queue + and configuration directories are set correctly and do + not contain any valuable files. + + <b>deport</b> Deport a secondary instance from the list of managed + instances. This deletes the instance configuration direc- + tory from the primary instance's <a href="postconf.5.html#multi_instance_directories">multi_instance_directo</a>- + <a href="postconf.5.html#multi_instance_directories">ries</a> list, but does not remove any files or directories. + + <b>assign</b> Assign a new instance name or a new group name to the + selected instance. Use "<b>-G -</b>" to specify "no group" and + "<b>-I -</b>" to specify "no name". If you choose to make an + instance "nameless", set a suitable <a href="postconf.5.html#syslog_name">syslog_name</a> in the + corresponding <a href="postconf.5.html">main.cf</a> file. + + <b>enable</b> Mark the selected instance as enabled. This just sets the + <a href="postconf.5.html#multi_instance_enable">multi_instance_enable</a> parameter to "yes" in the + instance's <a href="postconf.5.html">main.cf</a> file. + + <b>disable</b> + Mark the selected instance as disabled. This means that + the instance will not be started etc. with "postfix + start", "postmulti -p start" and so on. The instance can + still be started etc. with "postfix -c config-directory + start". + +<b>Other options</b> + <b>-v</b> Enable verbose logging for debugging purposes.
