Interesting that they didn't restore the old email addresses for people who kept it or didn't know their email showed up as *@facebook.com. Or at least it didn't seem like it from the profiles I viewed.
Because if they do that they will be unable to eavesdrop on your e-mail anymore, technically to forward an e-mail they have to receive it and resend. AFAIR SMTP protocol does not have redirects as HTTP does.
