It's funny how a 350 year old organisation can forget how to do the only thing they ever did.
As a matter of fact, what is now Postnord is a merger between the Swedish, Norwegian and Danish postal services, if I'm not mistaken. I don't think it's been sold, though. I think it's jointly owned by the three states. But I could be all wrong here. Their web site is down so I can't check! :D
