The problem with Scalix (along with brand 'Z') is that it isn't true open source; it's a cut-down free version. If you want the full functionality you have to buy the commercial version.
Many sites are now finding that end-to-end free software solutions such as Citadel (which is 100% GPL), Kolab, or even Horde are a better option -- there are no separate free and commercial versions, the entire package is available to everyone on the same terms.
