I started thinking of usernames as less secure passwords and therefore randomizing them a few years ago but never thought about the possibility of randomizing the email too. Not only does it help on the spam side of receiving mail but it can help on the login security front since knowing your email address no longer eliminates 33-50% of your login details. It sounds like this is a great enhancement in almost all cases: automated email randomization that is service dependent and also username randomization when you have a site with separate username than your email.
