Here (Belgium/Antwerp region) a while back people started putting a sticker on their mail box asking "no commercial mail/No unaddressed mail". This is now a general habbit, and the postal service (and commercial posters) tend to leave the mailboxes with the sticker alone. I know other regions and countries (eg. Holland) have this too.
It saves me from having to throw away heaps of paper.

Maybe something you could start over there?
