The first thing we should say is that it is a bit flaky. A number of items of post have gone astray (although that could have happened at the UK end) and at least one item has gone to a neighbour because a comma was interpreted as a number 1!
The key difference from the UK is that you don't get the post delivered to your door. Indeed, the doors do not have letterboxes. Instead, you are assigned a box at a nearby postal delivery station and the post-person drives up and pops all the post for the local area into the respective boxes. You're given a key for your box and you pop along each day (or whenever you want) to see if you have mail. You can imagine how our little faces light up when we find mail in our box! Our box is just around the corner from the house, so it's no big deal to walk (or in current weather conditions - more of that later - slide) over there to check. Here's our postal station...our box is on the bottom row of the middle section.
