Maybe put a QR code on your door and see where you get hits from? Alternatively set up a honeypot by gluing a fake bill to your mailbox as if it's a letter dangling out with some personal information on the envelope? It'd be interesting to see if anyone is running any automatic extraction over pictures of mailboxes.
