Zimbra Collaboration Suite (ZCS) is a groupware product created by Zimbra Inc., located in San Mateo, California, USA. The company was bought by Yahoo! in September 2007.[1][2] It consists of both client and server components. Two versions of Zimbra are available: an open-source version, and a commercially supported version ("Zimbra Network") with closed-source components.
The ZCS Web Client is a full-featured collaboration suite that supports email and group calendars using an Ajax web interface that enables tool tips, draggable items, and right-click menus in the UI. Also included are advanced searching capabilities and date relations (e.g. hover over the phrase "tomorrow at 6:00 PM" in an email message and the system will display any appointments at that time). Online document authoring, "Zimlet" mashups and a full administration UI are also included. It is written using the Zimbra Ajax Toolkit.
The ZCS Server leverages many existing open source projects such as Postfix, MySQL, OpenLDAP and Lucene. It exposes a SOAP application programming interface to all its functionality and also is an IMAP and POP3 server. The server runs on many distributions of Linux as well as on Mac OS X.
ZCS is compatible with proprietary clients such as Microsoft Outlook and Apple Mail as well as the open-source Novell Evolution, so that mail, contacts, and calendar items can be synchronised from these to the ZCS server. Zimbra also provides native two-way sync to many mobile devices (Nokia Eseries, BlackBerry, Windows Mobile).
Software license
ZCS Server is licensed under the terms of the Mozilla Public License (MPL), and accordingly requires that modifications made to existing files be given back to the community. ZCS Web Client alone is licensed under the terms of the Zimbra Public License (ZPL) which is derived from the MPL. ZPL adds an appendix to MPL requiring that any products derived from the ZCS Web Client source code display a "Zimbra Powered" logo that links back to the Zimbra website; see the license for details. The Zimbra Ajax Toolkit is licensed under the Apache License Version 2.0.
This ZPL license has generated some controversy in the open source community in that it is not an "open source license" as recognized by the Open Source Initiative and may violate sections of the Open Source Definition. This has led to some accusations that Zimbra amongst others are "abusing" the term "open source". [3] However, recently the Open Source Initiative also approved an attribution-based license (CPAL) similar in spirit to the ZPL license.
