It's amazing the differences between drivers. I've had the same (mostly) UPS driver for over 20 years. He will come through the gate and place packages in my, I call it a breezeway, some may call it a vestibule or mud room, and he rings the bell before walking away. He doesn't deliver all the time now, and the other driver I think is scared of my dog and leaves packages outside the front gate next to the fence.
No USPS delivery here so I can't comment on them, I have to go to the post office to pick up that mail. It really sucks because they are only open 4 hours a day.
Fedex is kind of a crap shoot, but they have gotten better at calling to try to locate the address and at least attempting delivery. Once upon a time, they would occasionally put them as deliverable or pass them off to the post office, back when the post office was open a full day.
DHL apparently doesn't deliver here. I've seen them here years ago but I have a camera coming through them, tracking just shows it "forwarded for deliver" only July 3rd and stops. I'm assuming they handed it to the post office, but at this point I have no idea.
*Edit *
Typing this made me check tracking, and I'm hoping "Delivered - Signed for by: LEFT LTR BOX " means it's at the post office
