no, no and no. this is really wrong, the passive aggressive, I-giving-you-a-hint-I-hope-you-are-getting-it approach. OP, your MIL is not visiting for a weekend, she moved in with you, you are both adults, you need to set very clear boundaries and expectations, obviously in a nice manner. as other posters suggested, you simply tell her with a smile, but firmly, I noticed you picked up our mail sometimes. please don't pick up our mail, it is something I do. thanks" and then change subject. or if you don't care that she takes it but are just afraid she may throw something away, just put a basket by the door in your apt and tell her to always put all the mail in there when she pick it up because you need to go through whatever comes in and do not throw away anything.
and this applies to everything else. if something does not work, tell her directly, clearly and nicely, and possibly right away. don't let her do something you hate for a year and then you blow up, you don't say anything she may think you are ok with it or even appreciate it. just speak up
