A given.
But other pertinent questions arise.
Could her emails be permanently deleted from her brew server? Can it be determined that some were? (an IT would know)
Was her home brew server being used as a access point for draft emails that were never sent but people with passwords could view?
Who else besides her used her server and why? It was reported last night that there were multiple email addresses listed for the home server - why and for what purpose?
Who else was aware that she was not using a government server to send and receive email?
This is just the tip of the iceberg. It's hard for me to see how she skates on this one. If Fauxahontas shows the slight bit of interest, Shrillary is done.
Don’t forget the message-drop possibility.
Compose an e-mail on an account but don’t send it, leaving it as a draft. The recipient knows the log-in for that particular e-mail account, reads the message and responds in the draft.
Recipient’s computer keeps almost no record. Server operator can delete draft message with almost no trace. No record of e-mail sent or received.
