Open Source License Terms for the Zimbra Collaboration Suite, Version 1.0

    PLEASE READ THIS AGREEMENT CAREFULLY BEFORE USING THE SOFTWARE. ZIMBRA, INC. ("ZIMBRA") WILL ONLY LICENSE THIS SOFTWARE TO YOU IF YOU FIRST ACCEPT THE TERMS OF THIS AGREEMENT. BY DOWNLOADING OR INSTALLING THE SOFTWARE, OR USING THE PRODUCT, YOU ARE CONSENTING TO BE BOUND BY THIS AGREEMENT. IF YOU DO NOT AGREE TO ALL OF THE TERMS OF THIS AGREEMENT, THEN DO NOT DOWNLOAD, INSTALL OR USE THE PRODUCT.

    1. License and Terms. Zimbra's software contains software components that are licensed by Zimbra from various open source distributors and redistributed by Zimbra to you in accordance with the provisions of their open source licenses.
    2. Collective Work. In addition to the individual copyrighted works from third parties that comprise the Zimbra product, the product as a whole (called a "collective work" in copyright law) is itself a copyrighted work owned by Zimbra (the collective work is defined as the "Zimbra Product"). The Zimbra Product is licensed to you under the Zimbra Public License (which is based on the Mozilla Public License) but each component is licensed to you under separate terms which are described below.
      1. This page will link you to the licenses that apply to the individual components of the Zimbra Product which is considered Exhibit A to this Agreement and is included as part of the Agreement.
      2. We have reviewed the licenses of all components of the Zimbra Product. All components are sublicensed to you with permission of the copyright owner and under the terms of their original licenses.
    3. Redistribution. If your use of the Zimbra Product is entirely internal to your company, you need not worry about license conditions requiring the distribution of source code that could affect your own proprietary software. However, if you distribute modified versions of Zimbra Product outside of your company, you may, in certain circumstances, have a reciprocal obligation to disclose your modifications to Zimbra and others. These obligations are found in the licenses listed on Exhibit A.
    4. Patent Defense. Some open source licenses also contain reciprocal patent grants and patent defense provisions that extend to you as a sublicensee of the software. Such license provisions are designed to protect the customers and users of open source software - including companies like yours - from patent infringement lawsuits. In certain circumstances, however, if you own patents relating to Zimbra collective work or its components, these license provisions may subsequently limit your ability to sue Zimbra and its open source licensors for infringement of those related patents.
    5. Trademarks. Many open source components, and Zimbra software itself, are also protected by trademarks. While you are free to copy and distribute open source software, you are not allowed to market it under those trademarks without separate licenses. Zimbra is a trademark of Zimbra, Inc. The trademarks of the licensors of our components are listed on their separate websites.
    6. Support. The Zimbra Product is licensed without any support. However, Zimbra is a full-support company. Even though open source licenses for Zimbra components offer few if any warranties, Zimbra, itself, along with our open source partners, will support the components of the Zimbra Product. We encourage you to review our separate service and support offerings.
