Open Source Collaboration Leader Zimbra Now Available on Ubuntu Linux

Zimbra, Canonical Ltd. offer full support for Zimbra Network Edition

SAN MATEO, Calif., May 14 -- Beginning today, users of Ubuntu, the fastest growing Linux distribution, now have a solution for open source, next-generation messaging and collaboration with the general availability of the Zimbra Collaboration Suite Network Edition for Ubuntu, the companies have announced.

The Zimbra Collaboration Suite -- a premier, enterprise-grade email and collaboration solution -- now supports the wildly popular Ubuntu version 6.06 LTS (Long Term Support) from Canonical Ltd., an operating system designed to be the ideal platform for enterprises seeking better stability and longer guaranteed support horizons. The combined offering provides organizations a cost-effective solution featuring a best-of-breed experience, effortless administration, regular updates and top-tier support.

"Zimbra offers Ubuntu users the ability to quickly, easily and securely collaborate in their work environment," said Mark Shuttleworth, founder of the Ubuntu Project. "It is the most cost-effective way to run a mission critical communication application today."

"We have seen an overwhelming anticipation for Ubuntu from our community members. Now demand has exploded in the form of tens of thousands of downloads, more community participation, and new inquiries from companies already using our Network Edition." said Satish Dharmaraj, CEO of Zimbra. "Together, Zimbra and Ubuntu form a strong partnership because we each boast thriving, passionate communities and are equally committed to providing users with desktop and server freedom of choice."

The release of the Zimbra Collaboration Suite Network Edition on Ubuntu will offer Zimbra users enterprise level functionality in an easy-to-use package. The new support will benefit users and developers alike; end users will have extended freedom of choice on the desktop and developers will be able to tap into the vast network of the Ubuntu community. Those running Ubuntu on the desktop will now also be able to take advantage of Zimbra Desktop, a complete AJAX-based collaboration client with offline capability.

"For a small business looking for innovative ways to increase worker satisfaction and productivity while lowering overall costs, the combination of the Zimbra Collaboration Suite and Ubuntu Linux is ideal - after 15 years of running Windows Servers, we've finally found a great reason to switch to open source," said Steve Blackmore, IT Director at "Zimbra and Ubuntu each have amazingly active forums, which are ideal for answering basic questions and reduce time wasted on troubleshooting. They function as an extension of my team and drastically reduce our total cost of ownership."

"We host over 10,000 users on legacy systems, and they have been demanding for a more flexible solution with a great user interface which we have found in Zimbra", said Christian Orellana, IT Director of CABO Communications A/S. "Ubuntu is our preferred operating system because it is so robust and easy to maintain. Zimbra announcing Ubuntu support was the tipping point for us to become a partner."
