Zimbra Collaboration Suite (ZCS) is a collaborative software suite, that includes an email server and web client.

Zimbra was initially developed by LiquidSys, which changed their name to Zimbra, Inc. on 26 July 2005.[2] The Zimbra Collaboration Suite was first released in 2005. The company was subsequently purchased by Yahoo on September 17, 2007,[3] and later sold to VMware on January 12, 2010.[4] In July 2013, it was sold by VMware to Telligent Systems[5] which changed its name to Zimbra, Inc. in September 2013.[6] It was then acquired by Synacor Inc on 18 August 2015.[7]

According to former Zimbra President and CTO Scott Dietzen, the name for Zimbra is derived from the song "I Zimbra" by Talking Heads.[8]

Edition

The software consists of both client and server components, and a desktop client. 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 Messaging Application Programming Interface connector to Outlook for calendar and contact synchronisation.[9]

Zimbra Desktop is a full-featured free desktop email client.[10] Development was discontinued under VMware's stewardship in 2013 but was restarted in February 2014. In addition, the webclient features an HTML5 offline mode starting with version 8.5.[11]

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.[12]

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 Linux distributions.[13] OS X Server support was dropped with version ZCS 7.0.

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, either through proprietary connectors or using the ActiveSync protocol,[14] both 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).[9]

Software license

Starting with version 8.5 the Zimbra Collaboration Suite (ZCS) source code is available under the terms of the GNU General Public License version 2 (backend) and the Common Public Attribution License version 1 (frontend).[15]

Previous versions were released under the Zimbra Public License (ZPL). 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 Zimbra, Inc. provides the license, rather than Yahoo!.[16]

  • MySQL (last used in version 8.0)
  • Apache Tomcat (last used in version 4.5)
