I'm really sick and tired of it personally. While it has cleared up quite a bit since I added a whitelist, its still HORRIBLE, I'm getting over 200 a week that get past the filter (Mainly 'Returned mail').
So I'm here to ask what everyone's solution is to this horribly painful problem to those of us who can not miss a single non-spam email, but must have an email listed clearly on somewhat popular pages.
