Today, while looking up some DNS settings, I saw that the MX record for mail.cosi.clarkson.edu had been set. So I configured the Zimbra image to support *@cosi.clarkson.edu addresses for COSI members and COSI use. So far, Zimbra seems very easy to manage, and also very quick and responsive. I really like how they have registered the right mouse button for a context menu, so that everything is very natural and intuitive to use.
Peace and chow,
