Yes, that's what I thought. However, both spamassassin on my machine and at 
another ISP don't do it: they simply add their "suspicion" in the header 
(that I can filter later with kmail filters).

Yes, it's in my "cpanel", but I don't have time to look in spamassassin's 
settings now. I turned it off at my ISP for mow.

Thanks for confirming the origin of the problem.
