Zimbra Collaboration Suite (ZCS) is a groupware product created by Zimbra, Inc., located in San Mateo, California, USA. The company was purchased by Yahoo! in September 2007. The software 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. These software versions are available from Zimbra for download and independent use, from Zimbra-authorized partners, and included with service from a Zimbra-authorized hosting provider.
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. Online document authoring, "Zimlet" mashups and a full administration UI are also included. 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 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, both through proprietary connectors, 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, iPhone with 2.0 software).
