Why would you leave package on the porch? In Poland postman has to contact someone in the home, and if nobody's there he leaves a note in the mail box "come to the post office and get your package - we will keep it for 2 weeks and then return it to the sender". And right now there's "packageomats" operated by some other companies - you can ask for your package to be delivered there and you need a passsword to take it out https://upload.wikimedia.org/wikipedia/commons/f/fc/Galeria_Przymorze_w_Gda%C5%84sku_(paczkomat_InPost).JPG https://upload.wikimedia.org/wikipedia/commons/f/fc/Galeria_... That's for people that don't have time when post offices are open, and aren't home when postman comes.
