It;s amazing how stupid people can be. At one time eight or so years ago I started getting emails for various people @jhall.co.uk. It seems that some UK company called J Hall must have been under the impression that rthey own that domain. I politely replied to the people sending the emails (after all it wasn't their fault; they were presumable just using the address that they had been given by the company for the people they were trying to contact) telling them that it wasn't the right address. I don't think I got many "thank you" mesages in response. Eventually it must have been sorted out, as the emails stopped.
