| I'm not 100% sure about this, but I think it is illegal to put anything in a mailbox that isn't official US Mail. Like for instance solicitors aren't supposed to put leaflets in mailboxes. If it's somebody else's letter that got mixed up with your mail that would be OK, but a letter you write to a person but don't put a stamp on it and mail it, just put it in their box yourself, I don't think so. |
