the biggest outlook email inbox

OK I googled for this and didn't find a forum, site, blog etc. Am shocked, perhaps I'm wrong and there is a whole community dedicated to this out there but is there a world record for the largest or biggest inbox? I ask because I know someone, let's call him CT who has 9314 message in his inbox. I was shocked. Perhaps with the devastating levels of spam around this is a futile question but it seems to me there must be some phenomenal inboxes around out there. Please share the facts, it started here.. Outlook, Outlook express, Eudora, Thunderbird, DreamMail, Incredimail, Entourage, I don't care what you use I just want to find the fullest!!!
