I have ISPConfig 3 installed on Ubuntu and I followed the perfect server guide when I installed it. The spam filters works good and all as it should be when the spam is in English. However I have swedish domains and I get tons of spam mails written in swedish, and they don't get filtered by the spam filter. English spam get filtered, swedish spam doesnt. How can I solve this? I assume I have to find some kind of spam filter database in swedish and add it to my configuration? Or is it done in another way? Where can I find such a list and how do I add it to my configuration?
