It seems likely the server was some version of Exchange.<p>Why would anybody in her right mind -- not to mention a powerful and visible government official -- operate her own email server?<p>In that timeframe there were several SaaS email providers that were very secure. A couple were even certified as HIPAA Associated Business Entities (for certain limited use cases). That&#x27;s a high standard of security.<p>It&#x27;s not hard to believe that servers for staff use operated by a department of the US federal government were ancient, poorly maintained, and vulnerable. It&#x27;s almost certain they had unreasonable usage limitations. &quot;Sorry, your mailbox contains 24 &#x2F; 25 megabytes so it&#x27;s almost full.&quot;  Plus, they probably thought they were cool because they had a T1.<p>But why couldn&#x27;t a powerful person like Secretary Clinton figure out how to contract with a competent SaaS?  I bet the big email provider on Amphitheater Road would have jumped at this project.<p>Finally, how come nobody involved in this cluster<i></i>*k has ever answered the question &quot;why?&quot;
