Please see use of Zimbra trademarks or logos below for more information.
What constitutes an inappropriate use of the Zimbra trademarks or logos?

By law and to ensure clarity for the greater Zimbra Community, we must ensure that the use of the Zimbra trademarks (name, logo, etc.) is subject to the following "fair use" guidelines.

Under fair use practice, you may describe your service as being based on Zimbra, such as "Acme hosted email using the Zimbra Collaboration Server," but you may generally not use the Zimbra name within your own branding such as "Acme Zimbra hosted email." Moreover, unless you are an accredited partner within the Zimbra Partner Program, you are not permitted to use any of the Zimbra logos other than their appropriate occurrence within the Zimbra software itself (see below).

Other examples of unauthorized use of the Zimbra trademarks include:

  1. Company, product, or service name — You may not use or register, in whole or in part, Zimbra, Zimlets or any other Zimbra trademark, including Zimbra-owned graphic symbols, logos, icons, or an alteration thereof, as or as part of a company name, trade name, product name, or service name except as specifically noted in these guidelines.
  2. Merchandise items — You may not manufacture, sell or give-away merchandise items, such as T-shirts and mugs, bearing Zimbra trademark, including symbols, logos, or icons, except pursuant to an express written trademark license from Zimbra.
  3. Zimbra logo and Zimbra-owned graphic symbols — You may not use the Zimbra logo or any other Zimbra-owned graphic symbol, logo, or icon on or in connection with web sites, products, packaging, manuals, promotional/advertising materials, or for any other purpose except pursuant to an express written trademark license from Zimbra, such as a reseller agreement.
  4. Disparaging Manner — You may not use an Zimbra trademark or any other Zimbra-owned graphic symbol, logo, or icon in a disparaging manner.
  5. Variations, takeoffs or abbreviations — You may not use a variation of the Zimbra logo for any purpose. Third parties cannot use a variation, phonetic equivalent, foreign language equivalent, takeoff, or abbreviation of an Zimbra trademark for any purpose. For example, the following are not acceptable:
    • iZimbra
    • ZimMail
    • Cimbra
    • Simbra
  6. Endorsement or Sponsorship — You may not use Zimbra logo or symbols, in a manner that would imply Zimbra's affiliation with or endorsement, sponsorship, or support of a third party product or service.
  7. Slogans and taglines —You may not use or imitate an Zimbra slogan or tagline.
  8. Domain Names — You may not use an identical or virtually identical Zimbra trademark as a second level domain name. For example, the following are not acceptable:
    • zimlets.com
    • izimbra.com
    • zmail.com
    • zimbramail.com

Please view the above as our reasonable effort to shed some light on the esoteric subject of Trademark Law. Please do not assume that this list represents a full accounting; rather we recommend you consult a lawyer if you are in doubt.

Am I allowed to provide the Zimbra Collaboration Server, Open Source Edition as a hosted (or on-demand) service using the Zimbra brand?

If you are not producing a derivative work of (that is, not making source code changes to) the Zimbra Collaboration Server (ZCS), Open Source Edition, then you are (by definition, since the software is unmodified) welcome to include the Zimbra copyright notices, trademarks, and logos as they appear in the unmodified Zimbra software. (Please note that we do not consider administrative configuration changes or the addition or removal of Zimlets to constitute modification to the Zimbra software.)

If you are producing a derivative work (that is, making changes to the source code) of ZCS, Open Source Edition, you are bound by the terms of the Zimbra open source licenses (see the Zimbra Collective License and the Zimbra Public License). Under the Zimbra Public License (ZPL), all derivative works of the ZCS Ajax/Javascript client must carry the "Zimbra Powered" logo in place of the original Zimbra logo. You are generally also required to open source any derivative works of the Zimbra Ajax/Javascript client if your Zimbra deployment will have "external" or third party users (see the Zimbra Licensing FAQ): The ZCS web user interface (UI) is itself software---the Zimbra UI is written in Javascript following the AJAX architecture. Under standard operation, Zimbra client software is automatically redistributed to the Hosted Service Provider's (HSP's) or Internet Service Provider's (ISP's) enduser customer. (All derivative works of Zimbra should also retain the original copyright notices.)

In either case (derivative work or original work), trademark law generally precludes you from using the Zimbra trademarks or logos to promote your product or service apart from their occurrence within the software (see guidelines above).

Am I allowed to rebrand the Zimbra Collaboration Server (ZCS), Open Source Edition for my internal use?

If you are not producing a derivative work of (that is, not making source code changes to) the Zimbra Collaboration Server (ZCS), Open Source Edition, then you are (by definition, since the software is unmodified) including the Zimbra copyright notices, trademarks, and logo's as they appear in the unmodified Zimbra software.

If you are producing a derivative work (that is, making changes to the source code) of ZCS, Open Source Edition, you are bound by the terms of the Zimbra open source licenses. Under the Zimbra Public License (ZPL), all derivative works of the ZCS Ajax/Javascript client must carry the "Zimbra Powered" logo in place of the original Zimbra logo (see the Zimbra Licensing FAQ), but you are more then welcome to include your own brand and logo in addition to the "Zimbra Powered" logo, subject again to "fair use" guidelines (see above). (All derivative works of Zimbra should also retain the original copyright notices.) You are generally also required to open source any derivative works of the Zimbra Collaboration Server if you redistribute Zimbra code, whether in source or binary formats (please see the Zimbra Licensing FAQ):

To prevent confusion about this point, our users can rely on this explanation of Zimbra's policy: If changes are made to the Zimbra Collaboration Server (ZCS) client or server software that are only redistributed on an organization's intranet, open sourcing is not required even if the organization's third party contractors receive copies of downloaded client software. (You must also ensure that any recipients of a derivative work of Zimbra Collaboration Client software are also bound by the terms of the Zimbra Public License (ZPL); see the Zimbra Licensing FAQ.) We do, however, interpret the ZPL to require open sourcing of derivative works if the redistribution of software is to third parties, such as would be the case, for example, with independent software vendors (ISVs), value-added resellers (VARs), hosted service providers (HSPs), internet service providers (ISPs), Original Equipment Manufacturers (OEMs), appliance manufacturers, or alternative support channels.

(All derivative works of Zimbra should also retain the original copyright notices.)
