The newest version is the beggining for a simple antispam. In this latest version I made it simpler to make your own list. With some time left I want to make the whole routine work in such way that it works on any given folder.
Be it so, the foldernames of the trash and spam folder ar different for each language.. I wonder hot that will work out.
