Petraeus, lover used al-Qaida email tricks

(London Telegraph) The CIA director and his biographer had a shared Gmail account and wrote some of their personal missives as draft emails, which were left in a draft folder or an electronic, “dropbox”.

They could each then access the shared account and open the other’s draft messages, reading them without the emails actually being sent.

Sending emails between two separate accounts leaves an electronic trail, including IP addresses that have been used.
