The Best Open Source Business Software and Solutions for the Business Enterprise

Zimbra is open source server and client software for messaging and collaboration - email, group calendaring, contacts, and web document management and authoring. The Zimbra server is available for Linux, Mac OS X, appliances, and virtualization platforms. The Zimbra Web 2.0 Ajax client runs on Firefox, Safari, and IE, and features easy integration / mash-ups of web portals, business applications, and VoIP using web services.

Ajax based web collaboration is at the heart of ZCS 5.0. The powerful web client integrates email, contacts, shared calendar, VoIP, and online document authoring into a rich browser-based interface. Also, their unique open source Zimlet technology makes it easy for you to include custom ‘mash-ups’ in the ZCS web client.

ZCS 5.0 also includes an elegant Ajax based Admin Interface plus full scripting tools to manage the ZCS server. Full support is provided for standards-based APIs (IMAP / POP / iCal / CalDAV) as well as MAPI and iSync, which enable seamless compatibility with other clients like Microsoft Outlook, Apple desktop suite, and Mozilla Thunderbird.

Zimbra also offers Zimbra Mobile, which provides over-the-air “push” synchronization to smartphones as well as a Connector for BlackBerry Enterprise Server.

The Zimbra solution also has a complete high security package including built-in anti-spam and anti-virus scanning.

Now Zimbra also features Archiving and Discovery, an optional component to save and search email for various compliance issues.
