Zimbra is open source server and client software for messaging and collaboration

What Company is offering:
Zimbra is open source server and client software for messaging and collaboration - email, group calendaring, contacts, and web document management and authoring
Zimbra provides open standards and a platform for developers, its tools can be integrated with some services that a lot of institutions already have established.
Why Is It Useful:
Considering the huge switching costs of a university with a communications system to support its current and past students, faculty and staff, signing on a new service like Zimbra is a big deal. It looks like Yahoo should be pretty satisfied with its acquisition of Zimbra.

Why It is In News Again:
Zimbra has landed more than a few deals, with some 200 educational institutions in 15 different countries for the Zimbra Collaboration Suite, making it a pretty far-reaching host of applications. That puts the suite in the hands of about 33,000 students, faculty and staff, 600,000 mailboxes.
