Roundcube

Roundcube is a free and open source webmail which provides a desktop like user interface. Roundcube is easy to install and configure for instance on a LAMP server. Roundcube requires a web server (for instance Apache2), an SMTP server (for instance Postfix), IMAP (for instance Dovecot) and a database (for instance Mysql).

This manual will work for Roundcube 1.0 and newer versions.

Installation

Install Apache2, Php5, Mysql

 apt-get install apache2 php5 php-pear php5-mysql php5-mcrypt php5-intl

Download installation package http://roundcube.net/

 wget http://softlayer-ams.dl.sourceforge.net/project/roundcubemail/roundcubemail/1.0.5/roundcubemail-1.0.5.tar.gz

Extract tar package

 tar -xjf roundcubemail-1.0.5.tar.gz

Move Roundcube to your preferred location on your server

 mv ~/roundcube /var/www

You can also install Roundcube using aptitude (we don't recommend doing it like this).

 aptitude install roundcube

If you do this, the configuration folder will be located in

 /etc/roundcube

Configuration

Define write privileges for www-data user (web server user) into the /temp and /logs directories.

Configuring Apache

Open the Apache configuration file

 nano /etc/apache2/sites-available/default

Add the following lines into the default file. You may need to change the folder path depending on where you installed roundcube.

<Directory /var/www/roundcube>

Configuring Roundcube

Our example configuration is available for download from https://github.com/Taistowiki/roundcube

Create file ~/roundcube/config/config.inc.php and copy the content below into that file. You can also use the installation program which is accessible from http://server_ip/roundcube/installer

 <?php
/* Local configuration for Roundcube Webmail */

Connecting DSN reading to your database using a writing operator. Written in the form (supports PEAR MDB2): db_provider://user:password@host/database

More examples: http://pear.php.net/manual/en/package.database.mdb2.intro-dsn.php

Supports Mysql, Pgsql, sqlite, mssql and sqlsrv. Be sure to note that Sqlite uses an absolute path: sqlite:////full/path/to/sqlite.db?mode=0646

 $config['db_dsnw'] = 'mysql://roundcube:password@localhost/roundcube';

Define the IMAP server's network address. If you leave this empty, then then you will be prompted for a login server as you try to log in. Using an array function you can get a list of different e-mail servers which you can log on to. For SSL or TLS connections use the prefix ssl:// or tls://

You can use the following variables:

• %n - hostname ($_SERVER['SERVER_NAME'])
• %t - hostname without the first part
• %d - domain (http domain$_SERVER['HTTP_HOST'] without the first part)
• %s - domain name after '@' in the login screen

For example: %n = mail.domain.tld, %t = domain.tld

$config['default_host'] = 'localhost';

Define the SMPT server's network address. When using SSL or TLS connections, use the prefix ssl:// or tls:// . If you leave this empty, PHP mail() function will be used.

You can use the following variables:

• %h - Users IMAP host name
• %n - host name ($_SERVER['SERVER_NAME'])
• %t - host name without the first part
• %d - domain (http domain$_SERVER['HTTP_HOST'] without the first part)
• %z - IMAP domain (IMAP host name without the first part)

$config['smtp_server'] = 'localhost';

The service provider's network address where users can get help for Roundcube. Do not link to the roundcube.net website!

$config['support_url'] = ;

This key crypts the user's IMAP password when it is saved in the database. Use a minimum of 24 characters.

$config['des_key'] = 'H=Mgd81+3Hn+VeKnU?h*bNX!';

List of additional components (plugins/ directory)

$config['plugins'] = array();
