The "open source" offerings of Zimbra and Scalix are badgeware. I really don't have a lot of respect for companies that offer both free and proprietary versions. When they do that, they are stating quite clearly: "We believe in proprietary software. We're going to charge money for the things we can get away with charging you for, and we're going to open source the pieces that we can't get away with charging you for, either because it's a commodity that we can't compete on, or because we helped ourselves to these open source underpinnings and we have to honor their licenses." Go with true end-to-end open source and select a GPL groupware server like Citadel or Kolab.
