someone knows if this An Post works with some local post
Most likely they work with THE local post office. An Post in Ireland is what Poszta Polska is in Poland. Don't worry about the status. I once waited for a package for four days and it said "out for delivery" for those whole four days. It may well be that it just arrived in Poland and is currently on it's way to Lodz.
If the postman can't get you at the address, he will leave a notice paper with the address where you can pick it up.
