If your objective is to avoid having communications archived and subject to subpoena, it does little good if the other persons you communicate with is on a .gov address, because HIS copy of the email will be archived. To be secure, ALL parties to the communication must be on private servers.
Tracking this down would lead to interesting data.
There would have to be strict rules regarding the emails.
For example, you cannot download the emails to your computer but must keep them on the server.
2. You cannot forward emails from a server address to anyone outside the server address.
3. Maybe even prohibiting emails to any outside address.
I’m wondering if these safeguards could be built into the server itself whereby the above would be automatic?
You’re right, it makes no sense to have your own server if you only have one email account. The fact that she had one with the no 22 tells you there were several.
Would be easy to subpoena her staff to find out what the rules were.
