High-end email and groupware is a domain where only few vendors can provide solutions. It is where companies like HP, Novell, or Scalix offer reliable and scalable products. And Scalix is the only one that has licensed parts under a free and open-source license (Scalix Public License). Scalix runs on Linux, is free for up to 10 users, offers a lot of possible features, ranging from caldav or syncml to clusters, and supports any client. Its flexible architecture gives you the freedom to choose your hardware platform, desktop client, security, directory, and storage infrastructure.

"With over one million mailboxes deployed, 140,000 Community Edition downloads, 5,500 community forum members and almost 700 corporate customers, the Scalix collaborating platform is the most field-proven Linux e-mail and group calendaring solution available to enterprise." - The Scalix website

With the right know-how, Scalix can be managed easily, and several thousand mailboxes are possible on a single server, Web GUIs and command-line tools help the administrator, and Scalix integrates easily with other professional tools, such as OpenVPN, Nagios, and others.

During its history of almost 20 years, many tools and programs have been developed for Scalix to help you with your routine work. While the official documentation has several thousand pages, which are not all up to date, this book gives a detailed overview from installation to advanced setups and best practices for configuration and security. It will help you implement and manage both the free open-source Community Edition and the Enterprise Edition of Scalix.The author provides both a concise description of the features of Scalix and an easy-to-use starting guide for those new to administering it.

Since 2000, he has published many books and courses used in Linux training sessions all over the world. Among that were three books for Packt (two on OpenVPN and one on Scalix Groupware). In the same year, he founded his own Linux consulting and training company, Feilner IT. He was also working as a trainer, consultant, and systems engineer at Millenux, Munich, where he focused on groupware, collaboration, and virtualization with Linux-based systems and networks.

Until 2015, he had been deputy editor-in-chief at the German Linux-Magazine, where he wrote about open source software for both printed and online magazines, including the Linux Technical Review and the Linux Magazine International (the U.S., UK, and Australia).

He regularly gives keynotes, workshops, lectures, and presentations at tech and political conferences in Germany.

He is interested in anything about geography, traveling, photography, philosophy (especially that of open source software), global politics, modern science, arts and literature, but always has too little time for these hobbies.
