So, the previous tennant left, didn't forward his mail, and some got delivered here. I know his new address. Can I just go to the post office, say this isn't mine, point out the name and hand them his address? Will they forward those envelopes to him? And, short of dragging the guy to the post office myself to have him fill out the change of address form, how can I get the post office to stop sending me his mail?
