There's a smart thing you can do, too, to prevent the Yahoo! Mail spam filters from becoming a problem themselves. The filters are good, but not perfect, and they can catch a message (newsletters in particular) you do want to receive now and then. To make sure you don't have to go reading your favorite newsletters in the Bulk folder in Yahoo! Mail, you can set up simple filters that keep it in your Inbox , no matter what. I have created such a filter for the About newsletters , for example.
