A mailbox filled to overflowing with catalogs, bills and letters is a telltale sign that you are out of town and no one's checking on your home for you while you're away. If you're leaving town and you won't have a house sitter bringing your mail in for you, you can have the U.S. Postal Service hold your mail while you are away, then you can get all of your missed mail at once when you come back to town. The Postal Service will hold your mail for any trips lasting between three and 30 days.
