That is impossible. If he was able to get one email every second (which is impossible itself) it would take over 4.2 billion seconds to get that many emails. 4.2 billion seconds is over 133 years (4.2 billion seconds / 60 / 60/ 24 / 365 = 133.18 years) so I really don't this guy has that many unread emails.
