Hi Kolab users, I've written an article about Kolab 3 and Anti-Spam: http://tobrunet.ch/2013/02/kolab-3-anti-spam/ I'm looking forward to comments, maybe you have some inputs what could be done better or differently. It would be great to collect some nice anti-spam techniques so that Kolab 3 rocks in fighting against spam. Cheers, Tobias
