Exchange targeted by open-source group

A new open-source effort dubbed OpenGroupware.org has been launched with the explicit intent to create applications that compete with Microsoft Exchange server products.

OpenGroupware.org is a sister project to OpenOffice.org, a community bent on developing open-source desktop applications that compete with Microsoft's dominant Office applications. The two groups identify themselves as separate but complementary and say they intend to work together to ensure interoperability.

"Just to be perfectly clear, (OpenGroupware.org) is an MS Exchange replacement," Gary Frederick, leader of the OpenOffice.org Groupware Project, said in a statement. OpenGroupware.org is "important because it's the missing link in the open-source software stack."

In the market for communication server software, or groupware, Microsoft ranks first in number of customers, followed by IBM, Novell, Oracle and a number of smaller companies that are hoping to fill specific niches.

Frederick highlighted the OpenGroupware.org launch as the culmination of a decade-long effort to map all the key infrastructure and standard desktop applications to free software.

Microsoft representatives could not immediately be reached for comment. However, in a recent memo to employees, Microsoft CEO Steve Ballmer identified open-source software as a significant challenge to the company's products.

OpenGroupware.org said it will build server applications running on the open-source Linux operating system and Sun Microsystems' Solaris OS to work with OpenOffice.org tools and other Linux and Windows groupware. Skyrix Software, a developer of Linux-based groupware, is contributing the OpenGroupware.org source code, based on its Skyrix 4.1 Groupware Server software.

The OpenGroupware.org software aims to provide document sharing functions for OpenOffice.org-based documents and allow collaboration among users of applications such as Microsoft Outlook, Ximian Evolution, Mozilla Calendar, Apple Computer's iCal, OpenOffice.org's client product known as OOo Glow, and other groupware clients.

"By configuring the OpenGroupware.org server together (after install) with the OpenOffice.org office suite and other groupware clients, (people) will be able to implement an integrated collaboration environment wholly composed of free software," Skyrix chief executive Jens Enders said in a statement.

Exchange Server
I find it interesting that OpenSource has targeted the Exchange Server product, but what I can't find is any documentation that even vaguely indicates WHY Exchange would be considered a superior product to any of its competitors, like Domino, on the AS400, or Postfix, on the Linux platform. Has anybody done a comparison on this? The only thing that I have been able to dig up is the MAPI interface. Beyond that, feature for feature, I can't find anything in Exchange that is not duplicatable in the other products.

what about zimbra
I though Zimbra was the alternative. There is an open source edition for it that can be modified.
