What if you leave mail in the box for the mailperson to take away, like dvds or any other type of mail if you're not going out that day and want them to take your mail for you? I would put up the red flag to let my mailperson know I had mail in the old mailbox. The only thing I can think of is to leave the red flagging device out, and keeping the box unlocked??? Anyone have any other ideas? Are the mailpeople used to this sort of thing?
