This year I have been scheduling USPS pick ups and you have to tell them where the package(s) will be and "Knock on Door/Ring Doorbell" is one of the options. I leave mine by the front door and so far no issues. They picked up ten package son Monday and all ten were scanned in by Wednesday. No physical receipt is left by the carrier but a notice os pick up completion is sent by email. It contains no data such as the tracking numbers of what was picked up, just the count.
