Roundcube in your Rimuhosting server
Roundcube is a modern webmail application featuring a slick interface and cool AJAX effects. It can be used as an interface to IMAP or POP3 servers. It requires PHP and a database. If you're in doubt of which database software to use, we would recommend MySQL.

Installation
The installation is simple. You can follow the instructions in
http://trac.roundcube.net/trac.cgi/wiki/Howto_Install or try to run our install script below. Note that we can't guarantee this will work for everyone. You should review this script before running in your system because, while we believe it's safe, it could damage your server.
Install script
wget -O round.sh http://bliki.rimuhosting.com/space/knowledgebase/linux/miscapplications/roundcube/round.sh
bash -x round.sh
This script should download roundcube, move it to /usr/local/roundcube, create a database and a 'roundcube' user in MySQL, and configure Apache. If everything goes as expected, you should only reload/restart apache and then access roundcube by going to to any of your sites, in the /mail path, so either of these would work:
http://<yourip>/mail
http://<yourdomain>/mail
(you should probably use https).
