I just setup the spam and didnt quite get the ham config right so it wasnt working. All my mail went into the spam folder, until I worked out what I had done wrong. I would recommend against having large volume mailing lists in the ham filter all the time. Maybe train on a few hundred messages and then dont bother. However I am using an old, slow machine so CPU is a major factor. Ian
