I just rented a house and when I check the mail the landlord has all kinds of mail coming to my mail box. It just don't look right to me, what do you think?

If you just rented the house, the LL may have lived there previously and that address may be on record in several places. It may take time to correct it. But there is nothing wrong in it. Just put the mail on the side for him to pickup. Or suggest he leave a forwarding with the Post Office.

Its been 2 years sense anyone has lived here.

Doesn't matter. He owns the property, he's entitled to use it as a mailing address.

Thank you.
