The real-time interception of contents of electronic communication is prohibited under the wiretap act,[12] while the Pen Register Act [12] provides protection for the interception of the non-content part of the electronic communication. The "From" and "To" fields along with the IP address of the sender/receiver have been considered as non-content information,[13] while the subject has been considered as the content.[14] Once the email is stored on a computer (email server/user computer), it is protected from unauthorized access under the Stored Communications Act (Title II of Electronic Communications Privacy Act).[15]
