README

Provides the HTTP client IP during IMAP connect to Dovecot in the form of an IMAP identifier for proper authentication penalty processing.

In reverse proxy configurations the actual client IP is resolved if the request originates from a trusted proxy.

Installation

The plugin can either be installed via Composer or manually. If the webmail server allows outgoing requests, Composer is the more comfortable option as it automatically resolves dependencies and simplifies updates.

Using Composer

⚠️ Note that it is not recommended to run Composer as root. Plugin installation requires script support enabled, as the RoundCube installer needs to move the downloaded plugin to the plugins directory and optionally can enable the plugin automatically.

  1. Get Composer.
  2. Within the RoundCube webmail root directory, add a new dependency to the plugin. Use dev-main as the version constraint for the latest in-development version.
    php composer.phar require 'takerukoushirou/roundcube-dovecot_client_ip:^1.0'
    
  3. Composer may ask whether to enable the plugin. Confirm with y.

To update the installed plugin to the latest version, simply run:

php composer.phar update --no-dev

Manual

  1. Download the latest release archive or checkout the latest release branch.
  2. Extract the contents into a folder named roundcube_dovecot_client_ip within the plugins directory of your RoundCube installation.

There are no external dependencies.

Repeat manual installation for updates. It may be advisable to keep multiple versions of the plugin in separate folders and use a symlink named roundcube_dovecot_client_ip from within the plugins directory to the latest version folder instead.

Configuration

To enable the plugin, add roundcube_dovecot_client_ip to the $config['plugins'] array in the RoundCube configuration file.
When using Composer, the installation routine will ask whether to automatically enable the plugin.

Options

On a fresh installation, navigate to the plugin directory and copy config.inc.php.dist to config.inc.php.
When using Composer, a copy is automatically created.

Edit config.inc.php within the plugin directory as needed.
All options and their accepted values are described in config.inc.php.dist.

Dovecot IMAP

The following settings need to be applied to the Dovecot IMAP server:

  1. Add the IP addresses or networks of your RoundCube webmail servers to the login_trusted_networks setting in your Dovecot IMAP configuration. This disables authentication penalty processing for the configured webmail server IPs and enables processing of the X-Originating-IP ident value with the actual client IP provided by this plugin.
  2. Restart Dovecot IMAP.

Afterwards, Dovecot connection logs should show the actual client IP of users instead of the webmail server IP in the rip (remote IP) field.
