I disagree - she had an email server set up in her bathroom- I bet it was just a standard install of Microsoft Exchange left with all the default settings. A high school kid could have ‘hacked’ in to it.
Considering Clinton’s Chappaqua address was listed as the contact address for domains clintonemail.com, wjcoffice.com, and presidentclinton.com, they had placed a target on them for hackers from the start.
I’ve been saying since we first learned she had an Exchange server in her bathroom, that we’d better be operating under the assumption that every country with an intelligence apparatus worthy of the name, friend and foe, has a complete copy of that server.
