Odd. In some other accounts I had seen that the emails supposedly came from Petraeus' own account. Now they are anonymous.
That way they could write and share email "drafts" without ever having to send them (and expose them).
Petraeus would write and save a draft without sending it...Broadwell would read the draft intended for her and delete it and write her own draft for P4.
But then Broadwell screwed up by sending a real email to Jill Kelley.
