Mail filters should have an option to access the address book so that multiple contacts can be place into them. This would allow for instant deletion of incoming mail that is not in the contact list.

i've heard some debates about having just a block senders list. The only problem with that is the list would constantly accumulate where as this method immediately narrows the problem down. How another alternative is to have a menu that adds senders to a safe list.

We do have a few existing bugs about spam filter ideas... some just a blocked senders list, some ideas include a "white list" of good senders, I believe. I'll try to reference a couple bugs numbers here after I look through the bug list.
