Thank you for your help, but I've already done it differently now. I'm using 
the spam filter capabilities of my mail reader (KMail). This uses an external 
spam filter (I've chosen CRM114). That's not optimal, because I have two spam 
filters now (on my desktop and my laptop), and no spam filter for my smartphone, 
but it works.
