If you mean the mail slot, it’s perhaps old-fashioned, since it’s a security weakness.
I remember seeing an old movie where a family kept the house key on a string just inside, so when the kid got home from school they could reach in, get the key, and unlock the door (parents were at work).
And a couple where someone put fire or explosives through the slot.
Side note: never seen a door like that in my life. Is it a regional thing or an old fashioned thing?
