San Mateo, California-based Scalix announced in July that it intended to launch the Scalix Community Edition Open Source version of its email, calendaring, and integration software having negotiated a new agreement with Hewlett-Packard Co, the original creator.

The first components were released this week with Scalix delivering the source code for its Scalix Messaging Services, Mobile Web Client, Search and Indexing Services, and Installer software, as well as the localization kit.

Even before that software was released the company had felt the benefit of moving to open source, according to chief executive, Glenn Winokur. Downloads of our software have increased sixfold since we announced our open source plans, he said. The community reaction has been phenomenal.

The Community Edition Open Source code is available for Red Hat Inc’s Enterprise Linux 3 and 4 as well as Novell Inc’s SUSE Linux Enterprise Server 9 and 10, Fedora Core 5, and openSUSE 10.1. An unsupported version is also available for Debian.

The code is based on Scalix 11, the forthcoming enterprise release version. Beta versions for Scalix 11 Enterprise, Small Business and Community are also now available. The Community Edition package was originally introduced in August 2005, but while that allows for free, unlimited software use, it does not grant code access.

Scalix plans to release more of the Scalix messaging software under and open source license during the first quarter of 2007.
