Is a 'letter box' the same as a mailbox that the postal service delivers our mail to? If it is, in the US it is illegal to put anything in those. We were told to keep handouts 'discreet' so that it didn't advertise that no one was at home (or just not answering their DOOR). Anyway, just wondering what a 'letterbox' was.

Only those who will risk going too far can possibly find out how far one can go.
