My house was built years before I moved in. I have nothing to do with the local mail delivery protocol. I now keep the dogs in until the the mail is delivered. It was only after the last regular mail guy retired that we had ANY problem. The issue is with the USPS giving door delivery routes to dogophobes.
No, the Postal Service didn't put the box on your house. The owner did. Time for you to move to street service or post office box, or maybe even GENERAL DELIVERY.
If door delivery causes you offense, take action to stop it!
