"Under fair use practice, you can describe your service as being based on Zimbra, such as "Acme hosted email using the Zimbra Collaboration Suite," but you generally cannot 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.
