The important role of the Zarafa community in Zarafa’s business model

April 22, 2015 by Felix Bartels  

With more details on future software development and a transition path for community users
Over the last 7 years Zarafa has made significant steps in establishing an ecosystem with partners, customers, community members and others. We’ve got a lot of energy of building an ecosystem together with you. At the same time Zarafa has been in a split between open source and close source components, where we were not able to unleash full potential in development and ‘distro’ adoption... Read full post

pam_mapi supports Zarafa 7.2

I am happy to announce that my pam_mapi supports Zarafa 7.2 starting with version 0.2.1. At the same time I am very sorry that this update did not happen before the final release but Zarafa unfortunately broke their own rules for compliance for integrations (mentioned on their old website) by simply not publishing a release candidate (RC) of Zarafa 7.2 but directly the final after the second beta (and no, beta and release candidate are definately not the same).
Some frequently asked questions... Read full post

Zarafa Collaboration Platform vs. SSLv3/POODLE vulnerability

October 15, 2014 by Robert Scheck   Comments (0)

, , , , , ,

The press already wrote about it: Bodo Möller, Thai Duong and Krzysztof Kotowicz from the Google Security Team discovered a design vulnerability in SSLv3 also known as "POODLE". I would like to try to answer some questions that popped up today regarding Zarafa and POODLE.
Important: Even the vulnerability seems to only affect HTTPS, it might (!) apply to other protocols/services as well (if an attacker has control over the packets that also contain secret data), thus Zarafa might be... Read full post

pam_mapi supports Zarafa's feature management

About 2.5 years ago I presented the first public version of pam_mapi. If you don't know pam_mapi, please have a look to my project.
Today I am happy to announce pam_mapi 0.2.0 - which is supporting Zarafa's feature management. What does this mean? Since Zarafa 7.0.0 some features can be enabled and disabled on a per-user basis. If e.g. IMAP is disabled for a specific user any IMAP login will fail. More about this can be read in the Zarafa documentation, section "8.7. Zarafa Feature... Read full post

Securing WebApp

, , ,

While we take care that the WebApp contains no programming flaws that can reduce security, there are a few things that you, as system administrator, can do to improve security. The most obvious one is to only allow access to WebApp when using SSL, but there is more. For this article, we will assume that you serve WebApp using Apache, but other HTTP servers have similar options.

Use TLS/SSL, get an official certificate
Anyone knows you should use SSL, and of course you can run a web server... Read full post

WebApp: The Feedback plugin

September 19, 2012 by Ivo Timmermans   Comments (0)

, , , , ,

Since a few weeks, there is a plugin that adds a "Feedback?" button at the top of the WebApp user interface. This button helps us, Zarafa, to understand the needs of our users. In this blog post, we will show what happens when you click it.

About two months ago, we upgraded our installation of Jira to version 5.1. This release comes with the concept of "issue collectors". This is a piece of javascript that you can insert in e.g. a web page to allow users of this page to give feedback. Every... Read full post

WebApp: the Dropbox plug-in

Consider the following: you're on your holiday location, on some sunny beach in a country where the beaches are usually sunny and very warm. You forgot to turn off your phone this day, and suddenly it beeps because it received a text message. It's your boss. He writes:

Please check your e-mail, it's important! -boss

Okay. You ignore it, turn off your phone and doze off again in the sun.

Then, later that day, sitting over dinner with the rest of your sunburnt travel... Read full post

The Zarafa WebApp uses GNU gettext to translate the strings to different languages. In this blog post, we asume that you are familiar with gettext; for an introduction please see

In the WebApp, the most commonly used function for translations is the _... Read full post

WebApp: Twitter widget (twidget)

August 6, 2012 by Ivo Timmermans   Comments (2)

, , , , , ,

The Twitter widget ("Twidget") is the integration of the Zarafa WebApp and the infamous Twitter service. With the twidget activated, any mention to a twitter account in your e-mail is detected, and the latest post of this twitter account are presented to you for direct usage and status. I always have it enabled, so I can use it when i get e-mails from new contacts; I can immediately see what kept them busy recently. This makes an initial contact much more interesting!

In this series, we have... Read full post
