Zimbra announced general availability of its Zimbra Collaboration Suite (ZCS) with the launch of ZCS 3.0. ZCS is an open source, enterprise collaboration system that reduces the cost and complexity of collaboration, and changes the way users and administrators interact with their e-mail and calendaring applications. ZCS 3.0 builds on the server and user interface technologies of the beta versions. These include integrated search, single-copy mail store, discovery, anti-spam and anti-virus/security capabilities on the back end, and an AJAX-based Web client that brings e-mail and calendar items to life through Web mash-ups on the front end. ZCS integrates the ability to subscribe to RSS and Atom feeds, and allows users to publish mailbox content such as calendar, contacts and mail folders via RSS. Zimbra’s calendaring application supports iCal and includes the ability to create and share public calendars, or import external calendars. ZCS has localizations underway in 10 languages, including Spanish, French, German, Italian, Portuguese, Dutch, Russian, Finnish, Japanese and Thai. The ZCS 3.0 Open Source Edition is free, and the commercially-supported Network Edition is available for $28/mailbox/year, which includes full product support as well as software subscriptions to new releases, updates and patches. Both editions can be downloaded. http://www.zimbra.com
