I backed out and did a new search, these are the only 7 that show up.
Did notice a couple of things, I see a @barackobama.com email address, so Obama had his own server too? Or just a registered domain name?
And the last email contains a couple of phone numbers. Probably no longer good, from years ago...
Barackobama.com was his campaign site. Last I looked the DNC appears to manage it.
