Junk mail auto-sort

Place a computer scanner's 'Actually scans the image' hardware strip along the top of your letterbox, and another one underside. As stuff is shoved through your door it gets scanned real time into a computer.

The image goes to an OCR program .. this is something that reads images and transfers it to text readable by computer (been around for years).

The computer analysis the text on the outside of the letter .. If, out of all the text on the letter, none has your name anywhere on it (or, defineable, anyone in your families name) -- the computer auto opens up a little box labelled 'junk mail' under the letterbox, and the post falls in (then shuts before next letter comes through).

If the sender doesn't even know your name, It's gonna be a flyer for the local pizza/curry place or some other kind of junk mail. Do as you please with the auto-sorted 'junk mail' box.

Half baked because --- if postie stacks the letters and posts 3 at the same time, only the top one gets scanned :( However if posted upside down it will work as I also put a scanner on the bottom side of the letterbox.
