Lots of responses here about people getting mail to the wrong gmail address. This never happens to me because I have a unique domain; that seems to cut down on the problem a great deal.
Most of the "wrong" email I get is genuine spam but it tends to be from companies I signed up for that have since gone out of business and sold my address to spammers, or companies that have had a data breach (naturally).
