Comment 3 for bug 411368

At CNET News they say: "Zimbra's server software is Java-based software that competes chiefly with Microsoft Exchange. People who need to access it to use e-mail, calendars and contact lists can use a basic Web browser interface or a fancier Ajax-based interface." (http://news.cnet.com/Zimbra-to-offer-Ubuntu-Linux-support/2100-7344_3-6181361.html).

Here is a quote from Mark Shuttleworth regarding the Zimbra Desktop (AFAIK you can run the server and have a feature-rich web frontend without installing that client software): "The Zimbra Desktop client will not only enhance the usability features of the world-class Zimbra Collaboration Suite, but will also provide the Ubuntu community with another compelling application for their desktop of choice." (http://ajax.sys-con.com/node/354316).

Don't know what you would need the Zimbra Desktop for. Don't know if it is of much use without the Zimbra server, either. This bug report seems to relate to the Zimbra server software, not to the client software.

Anyway: According to the article quoted from, Mark Shuttleworth's quote is nearly two and a half years old or even older. However, there's still no Zimbra to be found in Synaptic.
