Where is the dorm mailbox?

I had the same problem. It's a box in the wall right by the bathrooms, on the same side as the lift.

Thank you so much!

I didn't even know that mailboxes or even trashcans came standard with dorms until the mailman actually came and put mail into it and the maid (which also comes standard :joy: ) put trash into the trash reseptacle :flushed: :lol:
