When I moved out in the country about 4 years ago, I switched from many years of PO Box to a mailbox. Twice vandals have knocked down the boxes, and the wrong mail goes in the box every couple of weeks. Once my neighbor brought my bank statement to me. It has become obvious that the regular carrier does his job well but the relief carriers, well.... The road graders (dirt road) get closer and closer, and there is nothing there to anchor them to, so you have to hang onto the box to close it. We buried the thing way over 3 feet with concrete, but even so.... And they will likely never pave it because it would be a one way road then. (Of course, two cars have no trouble going by each other.)
Since my rural address is a plain old street address, I've had no trouble with
Amazon and the like, no matter who delivers. This is convenient. But I miss the security of that locked box, and expect to see a trend back to them. I won't mail my bills or anything of importance in my mailbox, I wait and take them to the PO.
Anyway, what the OP is talking about is certainly a problem for others, and ridiculous; guess we need more software people who live rurally.
