I have been working in the high-tech business for nearly 20 years. When you sign up, you are told in no uncertain terms that company business is to be conducted only on the company's email system. You are not to send or receive work-related email on your personal account.
I've also noticed that I can't send email directly to my various Congresscritters. I have to use a form on each Senator or Representative's web site, and those sites are in the senate.gov and house.gov domains.
So color me aghast that nobody in Hillary Clinton's circle of advisors told her that she shouldn't conduct business for the Department of State from her personal email domain. And equally aghast that nobody at the Department of State told her this.
People. I can't tell you how unlikely it is that her ISP or system administrator had sufficient security in place to provide adequate protection for email coming from the Secretary of State.
Yes, that is the sound of me banging my head against the nearest wall, especially when I read the crap coming out of the mouths of people defending her. IMO, this amounted to a security breech on the part of the Secretary of State. The Secretary's work email belongs on mail servers owned, supervised, and supported by the Federal government.
