I share an outer front door & porch with my neighbour who has a flat below me. If our mail gets delivered before the outer door is opened in the morning, it lies in the porch, and whichever one of us (myself/neighbour) leaves the house first, will put the respsective mail through each others letterboxes, and open the front door. However, my neighbour has taken to leaving my mail on my doorstep and opening the outer door so that the mail is in plain view and anyone could walk up and take it. We've asker her to stop doing this, but she continues (we don't have good relations and I''m sure she's just doing it to wind us up....).
What can I do to ensure my mail gets put through my letterbox? Is my neighbour breaking any laws? (doubt it...) Can the Royal Mail do anything? Or should I just do the same with her mail and maybe she will get the message?
