Roundcube webmail with SQLite on Debian

Roundcube is not available through apt-get in Debian 8 (Jessie), and the version which is in Debian 7 (Wheezy) is outdated. However, installing directly from the source is very easy.

I used SQLite, because these servers will only occasionally serve a few users for single domains. So a full database server seemed overkill. I selected /opt/roundcube as my install dir.

rcdir=/opt/roundcube

mkdir $rcdir
cd $rcdir

Check the latest version on the "Roundcube Webmail Downloads". As of November 2015, the version was 1.1.3. Copy the link for the "Complete" download.

version=1.1.3
wget https://downloads.sourceforge.net/project/roundcubemail/roundcubemail/$version/roundcubemail-$version-complete.tar.gz

Uncompress, copy out of the version-specific folder, and rename the original folder in case you need it.

tar xvf roundcubemail-$version-complete.tar.gz
rm roundcubemail-$version-complete.tar.gz
cp -rp roundcubemail-$version/* ./
mv roundcubemail-$version roundcubemail-$version.orig

Install dependencies

apt-get install php5 php-pear php5-sqlite

Initialize database

mkdir db
sqlite3 -init SQL/sqlite.initial.sql db/roundcube.sqlite

You will be left at the sqlite prompt. Type ".quit".

# sqlite3 -init SQL/sqlite.initial.sql db/roundcube.sqlite
 -- Loading resources from SQL/sqlite.initial.sql

 SQLite version 3.7.13 2012-06-11 02:05:22
 Enter ".help" for instructions
 Enter SQL statements terminated with a ";"
 sqlite> .quit

Set permissions

chown -R www-data:www-data temp logs db
chmod -R 775 db

Edit the Apache config file with your favorite editor. (I suggest mcedit or nano)

$EDITOR /etc/apache2/sites-available/webmail.conf

<VirtualHost *:80>
  ServerName webmail.example.com
  RedirectPermanent / https://webmail.example.com/
</VirtualHost>

<VirtualHost *:443>
  ServerName webmail.example.com:443

  SSLEngine on
  SSLCipherSuite HIGH:MEDIUM
  SSLProtocol all -SSLv2 -SSLv3
  SSLCACertificateFile   /etc/ssl/example.com_selfsigned_CA.pem
  SSLCertificateFile     /etc/ssl/example.com_web.pem
  SSLCertificateKeyFile  /etc/ssl/private/example.com_web.key

  ServerAdmin webmaster@alma.ch

  DocumentRoot /opt/roundcube

  CustomLog /var/log/apache2/roundcube-access.log combined3

  <Directory /opt/roundcube/>
    Options +FollowSymLinks
    AllowOverride All
    Order allow,deny
    Allow from all
  </Directory>

  <Directory /opt/roundcube/config>
    Options -FollowSymLinks
    AllowOverride None
  </Directory>

  <Directory /opt/roundcube/temp>
    Options -FollowSymLinks

  <Directory /opt/roundcube/logs>
    Options -FollowSymLinks
    AllowOverride None
    Order allow,deny
    Deny from all
  </Directory>
</VirtualHost>

You may also need to add NameVirtualHost *:443 to /etc/apache2/ports.conf

Check the Apache config. and reload

a2ensite webmail
apache2ctl -S
apache2ctl graceful

Edit the Roundcube config file.

cd $rcdir/config
cp -pf config.inc.php.sample config.inc.php
$EDITOR config.inc.php

Change these:

$config['db_dsnw'] = 'sqlite:////opt/roundcube/db/roundcube.sqlite?mode=0646';
  $config['smtp_server'] = 'localhost';

And add this:

$config['mail_domain'] = '%d'; # let new users get the right domain instead of the default "user@localhost"
