Hi Howtoforge friends! Today i was in the mood to create a new RoundCube package for ISPConfig2. This package contains RoundCube 0.4-stable, which is the current and latest version on the moment i add this thread. The new package can be downloaded here. Upgrade instructions (warning, your old sqlite.db will get lost): Login as root on your ISPConfig2 server. Execute the following commands: rm -r /home/admispconfig/ispconfig/web/roundcubemail rm -r /home/admispconfig/ispconfig/web/tools/tools/roundcubemail Login as admin into ISPConfig2 Click on > "Manager" > "Update Manager" > "Update" Add the URL: http://www.bb-hosting.org/downloads/ispconfig2/roundcubemail-0.4-stable.pkg Click on the "Install" button. You can access RoundCube 0.4 at http://www.yourdomain.tld:81/roundcubemail or under "Tools" within ISPConfig2 itself. (Tested on ISPConfig 2.2.37 on Debian Lenny) @Till Brehm and/or Falko Timme, feel free to add this package on www.ispconfig.org.
