Hi list, I am running spamassassin in kmail. As I got several spam from my provider although there is a spamfilter active, I trained my own spamfilter very well.
There are no false positives or negatives since many years. However, some spammails still appear (about 2-3 a week), but this is no problem and I use them to train my spamfilter better and better. All Spam will be moved into the wastepaperfolder (or whatever that thing is called). Of course, a spamfilter is best set at the receiving mailserver, but I made the experience, that all spamfilters from the mailproviders are low quality. I suppose, these are all commercial products, and we all know, what quality commercial products have, do we? Hope this helps a little bit. Best regards Hans
