Incident: DATABASE ERROR!

Posted on: October 29th, 2024 by

A database issue has just presented itself, and our operations team is investigating to find the cause and fix it.

Users who try to make use of the webclient will get the message:

DATABASE ERROR!
Unable to connect to the database!
Please contact your server-administrator.

Operations have a good lead on the issue, and we expect everything to be back online shortly.

You can follow the situation here on this blog.

2024-10-29 @ 10:22 UTC: The root cause of the issue has been identified to be a problem with a synch routine in the database cluster. The Operations team is working to get synchronization back in order. Meanwhile the login and use of the webclient is back. Users can login and use the facilities.

Please keep an eye on this blog, as there might be slipstream performance issues. The synchronization use a lot of resources and will most probably slow down the systems while running.

Cross-site Scripting (XSS) issue in the Kolab Webclient?

Posted on: December 5th, 2023 by

Lately we got a lot of questions at Support about a possible vulnerability in Roundcube, the Kolab Now webclient. The listing in question is  CVE-2023-47272 which upstream in the Roundcube development has been handled and patched.

To see the version of Roundcube running as the Kolab now webclient, login and press the ‘About’ button in the left side of the screen. This will reveal that Kolab Now is running:

Roundcube Webmail 1.5.6.3-30.1

This tells, that the fix was already installed, and that the Kolab Now webclient is not impacted by the vulnerability.

We are thankful for having an observant and active user base.

The Kolab skins

Posted on: September 11th, 2023 by

Some users probably remember when we first released the new Responsive skin back in 2018. Since then, the responsive skin has been developed further, some improvements were made, and the skin was promoted to be the default skin for new Kolab Now users.

We in the Kolab Now team love the Responsive skin, and we were not going to miss the old static skin when it was not deployed during the update to the latest version of the webclient. We had only received positive feedback about the responsive skin so far, but it turned out that some users still were very fond of the old look and feel.

Users were pointed to this knowledge base note. This answered the questions, though with some confusion. In this post we will lay out the options.

In the end of Wednesday it was thought that the root cause was found, and many users saw better performance for a while, but Thursday morning the performance dropped back to unacceptable levels.

How do server side (sieve) filters work again?

Posted on: September 19th, 2022 by

Kolab Now offers a mail filtering feature. That makes it possible to apply a series of actions to specifically selected incoming emails, so that incoming mail meeting a certain criteria can be automatically processed by the server and handled/organized according to the defined actions. For example the server can move the message to a specified folder, redirect it to another account, send a reply, discard, delete, etc for as long as the defined criteria is fulfilled.
