OK, I think I fixed it. It will work for the next couple of months, but you may need to clean it again. I tried pumping up the spam filter, but, with the free version, you cannot do that. I recommend deleting as much stuff as possible soon after you receive it. Also, marking spam messages as "spam" will help. Finally, getting off all mailing lists is the best thing -- most mailing lists are accessible on the web and you don't need to get email for it.
