The best thing is Merak Instant AntiSpam, though, server-side Bayesian spam filtering that can be trained via an instant messaging client plug-in as well as through online updates. The Merak Mail Server junk mail arsenal is completed by versatile challenge/response filtering. As-yet unknown senders that meet certain conditions (if their message has a certain Bayesian junk mail probability, for example) are sent a challenge, responding to which will authorize them.
Merak Mail Server also comes with a powerful WebMail interface (supporting secure S/MIME messaging) and pretty sophisticated groupware/calendaring features.
