Hallo ! Wie geht's ?

I've posted some days ago on reddit's r/dresden that I've posted my tourist postal cards for france on the wrong mailbox, on the red one of the modern post and not the yellow one of the Deutsch post, and I was asking if it will still arrived or not.

So to make the track of the post; just to say : my postal cards are arrived in France ! So to conclude, tourists, if you post your letter to the wrong mailbox, don't worry, modern post is conscientious and will correctly dispatch your letters ! (But be careful anyway !) Thanks for that !
