I do know my postman, he is called Tony, we do not like it when we get a different one, if he has to deliver parcels and I am not in he just goes through the gate into the garden and pops it somewhere under cover and leaves a note through the door, Maj knows him so lets him in and out.
I take in lots of parcels for both the next doors and sometimes across the road, because I appear to be the one most likely to be home at the right time, December last year was challenging as my hallway looked like a parcel depot, they all come round really quickly as soon as they are in and all say thank you lots so I don't mind. As my parents also live near they leave a note on their door saying to deliver it to me if they are not in.
A couple of times I have received flowers or chocolates because the item has been large and unwieldy and a right PITA to have in the hallway so all in all I do not mind here.
