Zimbra, a leader in open source, next-generation collaboration and messaging, today announced the Zimbra Collaboration Suite Network Edition for Mac OS X version 10.4 "Tiger" and Mac OS X Server version 10.4 "Tiger." The Zimbra Collaboration Suite is a leading open-source enterprise-grade email and collaboration solution and the Mac OS X version of the Zimbra Collaboration Suite includes support for iCal, Apple Mail clients and Xserve RAID storage.

Zimbra Collaboration Suite is cross-platform, with support for end-users on Macintosh, Windows, and Linux. Zimbra Collaboration Suite also supports users with traditional mail clients such as Outlook and Apple Mail, as an alternative user interface to the AJAX-based browser application.

"Since we released the open source version in November 2005 we've been overwhelmed by the interest and feedback we received from Apple customers and Zimbra forum members," said Satish Dharmaraj, CEO of Zimbra. "There was already clear demand for a Mac OS X version and since delivering the open source release, we've seen that demand explode, in the form of downloads, community participation, and requests from companies for our Network Edition. This release will be good not only for the existing Zimbra community, but for our growing Mac community."

"Tiger Server combines Apple's legendary ease of use, stability and performance with over 100 open source projects to make it the most advanced server operating system in the world," said Ron Okamoto, Apple's vice president of Worldwide Developer Relations.  "We're excited to see Zimbra using Apple innovation to deliver a powerful collaboration solution for Mac workgroups."

The release of the Zimbra Collaboration Suite Network Edition on Mac OS X will mark a milestone in Zimbra's commitment to innovation, open source and compatibility. The new support will benefit users and developers alike; Apple's server customers will be able to use Zimbra software with less interruption, and end users will have extended freedom of choice on the desktop.
