[opensuse] Fighting spam best practice

[Kenneth Aar, Grafikern.no]

Hi I wondered if anyone here has a take on how to best setup a SUSE 10.1 server to fight incomming spam for 10-100 clients. We are situated in Norway so most english language mails are spam. Most articles I found on google are old and outdated. So I was wondering if anyone has something fresh... Especially on how to sort out mails based on english language... -- Regards Kenneth Aar
