I feel Gary's pain a little.
I have a guy who presumably has the .com equivalent of my .co.uk address (although I don't actually know this).
From the emails I receive, he appears to own a Vauxhall, be a member of various motor clubs and does karate!
I do wonder if he ever thinks "why don't I ever get emails from *insert sender*?"
Or maybe he doesn't want said emails, so used an address that wasn't his on purpose?
