I've never heard of it outside the US. In Australia, you post something by putting it in a post box, they're located in shopping areas and have specified collection times, usually daily on weekdays. Of course, you can also go into the post office and deal with a human who will take the postage $ as needed. These days, the number of times I've posted something can be counted in low single digits per year. Mostly dealing with government forms that need signatures because stupid reasons.
