Zimbra

From Wikipedia, the free encyclopedia Jump to: navigation, search Zimbra Collaboration Suite Developer(s) Zimbra and VMware, Inc Stable release 8.0.3 (March 18, 2013; 3 months ago (2013-03-18)) Development status Active Type Collaborative software Licence Zimbra licensing Website www.zimbra.com

Zimbra Collaboration Suite (ZCS) is a groupware email server and web client, currently owned and developed by VMware Inc.

Zimbra was initially developed by Zimbra Inc and first released in 2005. The company was subsequently purchased by Yahoo! in September 2007, and later sold to VMware on January 12, 2010.

According to former Zimbra President and CTO Scott Dietzen, the name for Zimbra is derived from the song "I Zimbra" by Talking Heads.

Edition

The software consists of both client and server components. Two versions of Zimbra are available: an open-source version, and a commercially supported version ("Network Edition") with closed-source components such as a proprietary MAPI connector to Outlook for calendar and contact synchronisation.

Zimbra Desktop is a full-featured free desktop email client which is still supported in version 7 but has reached End of Life in version 7.2.2 and will be replaced with an HTML5 offline mode in version 9.

The ZCS Web Client is a full-featured collaboration suite that supports email, group calendars and document sharing using an Ajax web interface that enables tool tips, drag-and-drop items, and right-click menus in the UI. Also included are advanced searching capabilities and date relations, online document authoring, "Zimlet" mashups and a full administration UI. It is written using the Zimbra Ajax Toolkit.

The ZCS Server uses several open source projects (see the section, Included open source projects). It exposes a SOAP application programming interface to all its functionality and is also an IMAP and POP3 server. The server runs on many distributions of Linux as well as on Mac OS X

ZCS can synchronize mail, contacts, and calendar items with open-source mail clients such as Evolution and also with proprietary clients such as Microsoft Outlook and Apple Mail, but only through proprietary connectors available exclusively in the commercially supported version. Zimbra also provides native two-way sync to many mobile devices (Nokia Eseries, BlackBerry, Windows Mobile, iPhone, Android).

Software license

Zimbra Collaboration Suite (ZCS) source code is available under the terms of the Zimbra Public License (ZPL) which is derived from the Common Public License (CPL) and Mozilla Public License (MPL), and accordingly requires that modifications made to existing files, if distributed, be provided in source code form to the recipients under the same license. It also includes a clause requiring trademarks, logos, etc. be preserved making it an "attribution-style" open source license.

Categorically it is similar to the Open Source Initiative (OSI) Common Public Attribution License (CPAL).

The Free Software Foundation accepts the license as being a free software license and refers to it as being identical to the Yahoo! Public License with the exception that VMware provides the license, rather than Yahoo!.
