Zimbra Third Party Licenses, Version 1.1
The Zimbra Collaboration Suite (ZCS) includes several best-of-breed open source software technologies—projects that are crucial to Zimbra's operation and quality, both for the Open Source and Network Editions. For all such bundled technologies, the Zimbra team is committed to providing future updates, and for the ZCS Network Edition, Zimbra also provides additional quality assurance, product support, patches, and so on.
Each of these subcomponents is licensed under terms that have been approved by the Open Source Initiative (OSI) and are some of the most widely used Open Source Software (OSS) licenses and projects.
