Update: Kolab responsive skin

We’re pleased to announce an update for the Kolab Enterprise skin.

This update is a release of the new kolab Enterprise Responsive skin (known under the working title: Elastic). The release is available for for Kolab 16, on Red Hat Enterprise Linux 7, CentOS 7, Debian 8, Debian 9, Ubuntu 16.04 and Ubuntu 18.04,

The kolab-webclient meta package now provides (and requires) the new responsive kolab skin.


The skin can be selected from 'Settings -> Preferences -> User interface'. It is possible for an administrator to limit the list of skins available to end users (See below).




As the name indicates, the skin is responsive. It responds to the amount of screen space available on the host, and is hence equally useful on a large desktop monitor:

..and a mobile device:
















As mentioned, an administrator can configure the skins available to end users by adding the following to the config file /etc/roundcubemail/config.inc.php:

$config['skins_allowed'] = array('kolab');

..and remove the ‘skin’ item from the ‘dont_override’ setting in the same file:

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

If desired, change the default skin for those users who has no preference configured (in the same file):

$config['skin'] = 'kolab';

This last configuration eliminates the need for the ‘dont_override’ setting.
