I have lived in my current apartment for six months now, and am still receiving the last tenant's mail. My mailbox is clearly marked with my name, I've marked every single letter for this lady with "RETURN TO SENDER: RECIPIENT HAS MOVED" and I still get anywhere from 2-4 pieces of mail a day for her (she must have been popular, because people write to her all the time!) This usually isn't such a big deal but I have seriously received 16 Christmas cards this week for her.
Is there anything I can do? The landlord doesn't know where she moved to, and every note I leave for the mail carrier seems to be ignored.
