TMP

Zip download

• Shipped by RoundCube
• Plugin name: zipdownload

Adds an option to download all attachments to a message in one zip file, when a message has multiple attachments. Also allows the download of a selection  of messages in one zip file. Supports mbox and maildir format.

Rename the template of config file and adjust the few options as you like. I left the default options intact.

mv config.inc.php.dist config.inc.php

Enigma

• More info here
• Requires: gpg (gnupg and libgpg-error on Slackware systems)
• Shipped by Roundcube
• Plugin name: enigma

Update: the enigma plugin included in 1.3.1 version seems to be not compatible with the old version of Crypt_GPG

This plugin adds support for viewing and sending of signed and encrypted messages in PGP (RFC 2440) and PGP/MIME (RFC 3156) format.  The plugin uses gpg binary on the server and stores all keys (including private keys of the users) on the server. Encryption/decryption is done server-side. So, this plugin is for users who trust the server.

Create a config file

cd /var/www/roundcube/plugins/enigma
cp -p config.inc.php.dist config.inc.php

The keys are stored by the server in the enigma/home dir. Let's move that dir to a folder that is not accessible from the web and assign to apache write permissions

mkdir -p /var/www/roundcube-enigma-home
chown -R root:apache /var/www/roundcube-enigma-home
chmod -R g+w /var/www/roundcube-enigma-home

Now modify your apache configuration to grant proper permissions to apache in the newly created dir:

Require all granted

Don't forget to restart your web server, for example:

apachectl restart

Now modify the enigma config file to point to the new home dir:

$config['enigma_pgp_homedir'] = '/var/www/roundcube-enigma-home';

The enigma plugin requires that the Crypt_GPG library is installed exactly in your /var/www/roundcube/plugins/enigma/lib/Crypt_GPG dir. Considering that roundcube resets the default include_path php variable (which is set by php.ini to /path/to/php/lib), if you choose to install it using pear you will get a "Server error". So let's manually download and install the package in the proper folder

cd /var/www/roundcube/plugins/enigma/lib
wget http://download.pear.php.net/package/Crypt_GPG-1.6.2.tgz
tar xzf Crypt_GPG-1.6.2.tgz
ln -s Crypt_GPG-1.6.2/Crypt
chown -R root:apache Crypt*

The set up of the certificates is easy. Refer to this blog page for more info.

Other plugins

I leave here the documentation for plugins that I've used in the past or that it's not valid anymore for the current version of Roundcube, in case it can still be useful for someone or for myself in the future.

rcguard

This plugin logs failed login attempts and requires users to go through a reCAPTCHA verification process when the number of failed attempts go too high. This provides protection against automated attacks.

• Installed via composer dsoares/rcguard
• Plugin name: rcguard

mv config.inc.php.dist config.inc.php

You have to obtain a key from http://www.google.com/recaptcha. Put the key in your config file:

> nano config.inc.php

// Public key for reCAPTCHA
$config['recaptcha_publickey'] = 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx';

// Private key for reCAPTCHA
$config['recaptcha_privatekey'] = 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx';

Create the mysql table where to store the logs of all failed attempts. IPs are released after a certain amount of time.

> mysql -u root -p
mysql> use roundcube;

CREATE TABLE `rcguard` (
  `ip` VARCHAR(40) NOT NULL,
  `first` DATETIME NOT NULL,
  `last` DATETIME NOT NULL,
  `hits` INT(10) NOT NULL,
  PRIMARY KEY (`ip`),
  INDEX `last_index` (`last`),
  INDEX `hits_index` (`hits`)
) ENGINE = InnoDB CHARACTER SET utf8 COLLATE utf8_general_ci;

quit;

That's it. The captha will be active after 5 failures. You can set this number in the config file.

Different themes and translations of recaptcha are available. Simply edit rcguard.js. For documentation, see:  https://developers.google.com/recaptcha

autologon

Performs an auto login from an external page

• Shipped by Roundcube
• Plugin name: autologon

You have to modify the default Thomas Bruederli's sample plugin like this (eventually change to $_GET):

<?php

/**
 * Sample plugin to try out some hooks.
 * This performs an automatic login if accessed from localhost
 *
 * @license GNU GPLv3+
 * @author Thomas Bruederli
 */
class autologon extends rcube_plugin
{ 
  public $task = 'login';

  function init()
  {
    $this->add_hook('startup', array($this, 'startup'));
    $this->add_hook('authenticate', array($this, 'authenticate'));
  }

  function startup($args)
  {
    $rcmail = rcmail::get_instance();

    // change action to login
    if (empty($_SESSION['user_id']) && !empty($_POST['_autologin']) && $this->is_localhost())
      $args['action'] = 'login';

    return $args;
  }

  function authenticate($args)
  {
    if (!empty($_POST['_autologin']) && $this->is_localhost()) {
      $args['user'] = $_POST['_user'];
      $args['pass'] = $_POST['_pass'];
      $args['host'] = '[localhost | mail-server-IP]';
      $args['cookiecheck'] = false;
      $args['valid'] = true;
    }

    return $args;
  }

  function is_localhost()
  {
    return true;
//    return $_SERVER['REMOTE_ADDR'] == '::1' || $_SERVER['REMOTE_ADDR'] == '127.0.0.1';
  }

}

Use a form like this one in your CMS page:

<form name="form" action="http://your.webmail.url/" method="post">
<input type="hidden" name="_action" value="login" />
<input type="hidden" name="_task" value="login" />
<input type="hidden" name="_autologin" value="1" />

<table>
<tr>
    <td>Utente</td>
    <td><input name="_user" id="rcmloginuser" autocomplete="off" value="" type="text" /></td>
</tr>
<tr>
    <td>Password</td>
    <td><input name="_pass" id="rcmloginpwd" autocomplete="off" type="password" /></td>
</tr>
<tr>
    <td colspan="2"><input type="submit" value="Login" /></td>
</tr>
</table>

</form>

Logout redirect

This plugin is not tested against Roundcube 1.4.1

In case you have installed the autologon plugin this one could be useful to redirect users to the home page of your site upon logout.

• Info: http://www.std-soft.com/bfaq/52-cat-webmail/105-logout-redirect-fuer-roundcube.html (german)
• Download local copy
• Plugin name: logout_redirect

cd /var/www/roundcube/plugins
wget http://notes.sagredo.eu/files/qmail/tar/RC-plugins/logout_redirect_rc0.5_v1.2-MN.tar.gz
tar xzf logout_redirect_rc0.5_v1.2-MN.tar.gz
cd logout_redirect
chown -R root.apache logout_redirect
chmod -R o-rx logout_redirect

The plugin logout_redirect must be the last in the list of plugins in the main.inc.php otherwise the subsequent plugins will no longer run.

Configure like this editing the config.inc.php inside the plugin's config folder:

$ config['logout_redirect_url'] = 'http://www.yoursite.net';

quickrules

Adds a button to the message list to allow the quick creation of rules in the SieveRules plugin. Information from selected emails is used to prefile the new rule form.

• Version: 2.0
• Requires: managesieve plugin
• Plugin name: quickrules

This package is abandoned and no longer maintained. No replacement package was suggested. I leave this documentation here, to be used with 1.3 and earlier versions of Roundcube.

The plugin version from github doesn't work with 0.9.2. I managed to install the new skin inside the old 0.6 version of the plugin and now it works fine. You can download my modified version from here.

cd /var/www/roundcube/plugins
wget https://notes.sagredo.eu/files/qmail/tar/old-RC-plugins/quickrules.tar.gz
tar xzf quickrules.tar.gz
chown -R root.apache quickrules
chmod -R o-rx quickrules
