I've been using Kolab for my mail/collaboration software for home about 4 years. Right now, the hard drive on the machine I'm running on is failing. I have other hardware on which to run the new mail server, however, I am trying to decide the best suite to use. I can stick with Kolab, as there is a new release, however the installation is kind of clunky on Debian (basically installing RPMs). The main features I am looking for, in order of priority:
* Good-to-excellent antispam (bayesian filter, spamassassin, but extensible) * Shared calendaring with Palm integration * Preferably opensource and cost free * (preferably) Postfix-based Now kolab has been falling down on the anti-spam job, but part of this may be because of the failing drive. I see myself having the following options. 1. Stick with Kolab on the new server. 2. Scalix 3. Zimbra 4. Hula >From what I have read in my initial perusal, Zimbra and Scalix, while commercial, both have free/community versions. I'm looking at less than a dozen accounts, and most will be accessed by Linux (kde, gnome or enlightement). Zimbra seems fairly mature. Hula would also be a consideration, however, their documentation on antispam is almost non-existent, and the sections that do have information generally have "Coming soon..." Does anyone have experience deploying any of these servers? How painful is migration of existing mail stores to the other systems? Am I missing any possibilities?
