Zimbra is an enterprise-class email, calendar and collaboration solution built for the cloud, both public and private. With a redesigned browser-based interface, Zimbra offers the most innovative messaging experience available today, connecting end users to the information and activity in their personal clouds.
Zimbra’s Open Source Community
Since the inception, Zimbra has been a community. All of our Zimbra Collaboration Open Source Edition software, documentation and innovation has been created, tested, used, and discussed openly by people like you participating in our Open Source Community. Our contributors diagnose bugs, fix bugs, translate programs, submit patches, point out deficiencies in documentation, answer community questions, submit killer applications, alert us to something that needs tweaking, and write new software. No matter how you contribute, we welcome new ideas and contributions for the advancement of greater shared knowledge and a better Zimbra Collaboration product.
So jump in! Zimbra Collaboration Open Source Edition is available for you to test, evaluate, deploy, customize and improve.
Special Note: Zimbra recently made key changes to its open source software licensing in order to build an even stronger foundation for community-powered innovation. With the release of Zimbra Collaboration 8.5, Zimbra officially moved to Open Source Initiative-approved licenses. The Zimbra Open Source Edition Web Client Code is released under the Common Public Attribution License, version 1.0 (CPAL v.1). The Zimbra Open Source Edition Server Code is released under GNU General Public License, version 2 (GPL v.2). The Zimbra Open License Community Zimlets Code is released under the Common Public Attribution License, version 1.0 (CPAL v.1). Versions prior to version 8.5 will remain under the Zimbra Public License 1.4. By moving to OSI-approved licenses, Zimbra hopes to increase contributions from the open source community and increase compatibility with other open source projects, so that customers, partners, and end users receive greater benefit from integration across the open source software ecosystem.
