Hi, Thank you for tips but no one solves my problem. I switched off spam filters, removed $HOME/.spamassasin but still have the following first lines in 'top': 6244 horvatha 15 0 238m 39m 19m S 82.4 9.1 2:28.36 evolution 2121 root 15 0 13812 2972 2268 S 12.6 0.7 2:20.31 gdm-binary What is this gdm-binary? If I exit from Evolution it disappears also. Is it important? Thank you in advance, András
