Scalix email and calendaring, HP OpenMail, and Samsung Contact: these three names stand for some of the most powerful open-source-based groupware solutions available. This book sets out to explain their fundamentals to Linux administrators.
Since the early 90s, Hewlett Packard had earned many awards for its mail server, and OpenMail was said to be more scalable, reliable, and better performing than any other mail and groupware server. After only a few years, the product had managed to conquer the United States' fortune 1000 almost entirely. Scalix Inc., a member of the Xandros family, has continued this story in the last years: several reviewers claim that it has better Outlook support than MS Exchange.
With the right know-how, Scalix can be easily managed. 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, be it OpenVPN, Nagios monitoring or others.
During its history of almost 20 years, many tools and programs were developed for Scalix to help the admin in his/her daily work. While the official documentation has several thousand pages, which are not all up-to-date, this book tries to give a detailed overview from installation to advanced setups and configuration in big companies.
With this book, I want to provide both a concise description of Scalix' features and an easy-to-use introduction for the inexperienced. Admins, consultants, and teachers will all find this book a helpful base for daily work and training. Though there are many other possible ways to success in the described scenarios, the ones presented have been tested in many setups and have been selected for simplicity reasons.
High-end email and groupware is a domain where only few vendors can provide solutions. This is not the realm of Microsoft, and it has never been. It is where companies like HP, Novell or Scalix offer reliable and scalable products. And, Scalix is the only one that has licenced parts under a free and open-source licence. The software is free for up to 10 users, easy-to-use, and offers a lot of possible features ranging from caldav or syncml to clusters.
