Messages Server is a component of OS X Server from Apple Inc. It was first introduced as iChat Server with the release of Mac OS X Server 10.4, and was upgraded to version 2 with the release of Mac OS X 10.5 Server in October 2007.[1]
Version 2 of the software is based on jabberd2 2.0s9 and supports server federation,[3] which allows chat clients to talk directly with other systems that support XMPP. It also supports server-based chat archiving.[4]
