Well, an active filter - [treating everything as spam, and filtering EVERYTHING off, save what you manually instruct it to pass] could work.

I get a few e-mails every week from people I have never heard from, commenting on something I've written, pro or con. So I can't use a filter that screens out all "unknowns." I value those e-mails, and want to receive them.
