Maybe if you run your own ISP it shoes up as a lower number? Probably just a bug that they'll clean up in a future update.
I did, however, impress a couple of people by showing them how many emails I "had." Yeah, I told them they were all from match.com... :)
First post - thank you all for having me here... :)
My thought is that the "2 billion" number is the amount of emails in the provider's system. For instance, earthlink, network solutions, pacbell, gmail...etc.
Just an idea - cheers!
