we had set up a campaign to reduce junk mail in Belgium
Through the local authority we provided schools, bussinesses and individuals
with a sticker: 'refused: return to sender' and a little explanation why the
receiver found the mail inappropriate.
It works very well!
As far as I know; international postal regulations provide the possibility
to refuse any mail without motivation.
Kind regards
