See the configuration file for a fast overview.

When changing a configuration parameter in the plugin configuration file, you must not forget to trigger a plugin list update through the plugin management interface, else your changes won't be taken into account.

Roundcube plugin definitions

This plugin make it possible to install any Roundcube plugin by adding plugin definitions in the plugin configuration file.

Basic Roundcube plugin definition

A basic Roundcube plugin definition looks as follows:

    'name' => [
        'enabled' => true

Here we provide a definition for the name plugin and we tell that it must be enabled.

Installing a Roundcube plugin through the PHP dependency manager (Composer)

Most of time, you will have to go one step further by telling how to get and install the plugin. This can be done by adding a composer section as follows:

    'name' => [
        'composer' => [
            'require' => [
                'vendor/name' => '^1.0'

Basically, a composer section is what you would put in a composer.json file to make the PHP dependency manager (Composer) able to download and install a PHP dependency, here, a Roundcube plugin.

In the example above, we require the vendor/name composer package.

You can learn further about composer by looking at the official documentation.

Roundcube plugins not available through nor through

Sometime, a plugin is not available through official Roundcube plugin repository, nor through repository. In such a case and if the plugin provides a composer.json file, you can define your own repository as follows:

    'name' => [
        'composer' => [
            'repositories'    => [
                'type' => 'path',
                'url'  => PERSISTENT_PATH . '/plugins/RoundcubePlugins/name',

In the above example, we define a path repository in which composer will look for the name plugin. We assume here that the Roundcube plugin has been downloaded manually under the <PERSISTENT_PATH>/plugins/RoundcubePlugins/name directory.

Getting a Roundcube plugin from a Git repository

It is possible to grab a plugin from a Git repository automatically by adding a git section as follows:

    'name' => [
        'git'      => [
            'repository' => 'https://domain.tld/vendor/name.git'

By doing this, the repository will be automatically cloned under the <PERSISTENT_PATH>/plugins/RoundcubePlugins/name directory (eg: /var/www/imscp/gui/data/persistent/plugins/RoundcubePlugins/repository_name)

However, note that usage of the git section above is only needed if the Git repository holds more than one plugin. Most of time, you can do the same thing through composer, using a VCS repository.

For instance:

    'name' => [
        'composer' => [
            'repositories' => [
                'type' => 'vcs',
                'url'  => "https://domain.tld/vendor/name.git"

Roundcube plugin configuration

A last step is needed if you want to override default Roundcube plugin parameters. To to so, you can add a config section as follow:

    'name' => [
        'config'  => [
            'file'       => '',
            'include_file' => '/foo/bar/baz.php,
            'parameters' => [
                'param1' => 'value',
                'param2' => 'value'


  • file is an OPTIONAL parameter that allows to override default plugin configuration template filename
  • include_file is an OPTIONAL parameter that allows to provide the path of a file that will be included in the Roundcube plugin configuration file. Note that the file must be readable by the control panel user (eg: vu2000). A good place for that file could be the <PERSISTENT_PATH>/plugins/RoundcubePlugins directory.
  • parameters: is an OPTIONAL parameter that allows to provide plugin parameters. Those parameters will be added at the end of the plugin configuration file

To resume, if you want to override a Roundcube plugin configuration parameter, you must not edit its configuration file directly. Instead, you must process as above. This is needed because the i-MSCP Roundcube package doesn't save your changes on reconfiguration/update.

Configuration script

Sometime a plugin can require more configuration works. For that purpose, you can provide your own configuration script as follows

    'name' => [
        'config'  => [
            'script' => '/foo/bar/'

In the above example, we provide the /foo/bar/ Perl script. That script will be executed automatically with the current action passed as first argument:

  • On Roundcube plugin pre-configuration: /foo/bar/ pre-configure
  • On Roundcube plugin configuration: /foo/bar/ configure
  • On Roundcube pre-deconfiguration: /foo/bar/ pre-deconfigure
  • On Roundcube deconfiguration: /foo/bar/ deconfigure

Note that the script must provides a correct shebang.

For instance:

  • #!/usr/bin/env perl for a Perl script
  • #!/usr/bin/env php for a PHP script
  • #!/bin/sh for a shell script
  • ...

See for an example.
