This may seem like an odd question, but the question is an honest one and I don't know what's going on as I've lived in Europe the past 9 years and may be out of touch. I've had 3 items come to me via USPS to include two items I'd ordered (one of which was a supply of pipe tobacco) and the other a piece of official government correspondence (I work for Uncle Sugar) and all have been deemed undeliverable, as I assume I've not been home, because I've been at work. Is there some new rule or trend with postal operations that require someone to be at home if no signature is required for delivery? I made an initial visit to my local post office to inquire on the location of all 3 items, and all 3 seem to have not been scanned since marked undeliverable over the past 3 weeks. I am asking to ensure something with deliveries hasn't changed before I go in again with a more firm attitude. The only thing that sticks in my mind is some news articles that concerned porch theft of delivered parcels over the holidays. Nothing has been left in my mailbox indicating the item wasn't able to be delivered.
