Spark and Zimbra


Zimbra 5.0 or higher supports the XMPP (Jabber) protocol for instant messaging. It stands for eXtensible Messaging and Presence Protocol (XMPP) (formerly known as Jabber) which is an open sourced, XML-inspired protocol for near real time, extensible instant messaging (IM) and presence information (a.k.a. buddy lists).

XMPP compatible clients, such as Spark, can be used to connect to the Zimbra server. Users can then add buddies from their Zimbra Server into Spark without having a need to connect to a Third Party service such as AIM or MSN. This allows users to keep their home or personal instant messaging account separate from their work or professional account. Additionally, users can use the company/corporate/family Zimbra Server without signing up for another IM account from a Third Party Vendor. If you have an account on the Zimbra Server, you already have a XMPP/Chat account.

Spark is created by IgniteRealtime/Jive which also produces the Wildfire/Openfire portal software, from which Zimbra's server side IM branches from.
