Interloc, runs an online rare and out-of-print book listing service, and as part of its services provides certain book dealer customers with an electronic mail address. In its ordinary course, an e-mail message (“e-mail”) is transferred from one computer to another before it reaches the addressee. During the transmission route, an e-mail is handed to a Message Transfer Agent (MTA), which stores the message locally. The message is routed through the network from one MTA to another until it reaches the recipient’s mail server, which accepts it and stores it in a location accessible to the recipient, at which point the final delivery is deemed to be completed. The final delivery process places the message into storage in a message store area. Usually a separate Mail Delivery Agent (“MDA”) is required to retrieve the e-mail from the MTA in order to make final delivery. Interloc used a program known as “procmail” as its MDA, which operates by scanning and sorting out e-mail and an MTA computer program known as “sendmail”. Interlock employees were directed by the defendant to edit their version of procmail to intercept and copy all incoming communications from one of their competitors - Amazon.com. As a result, all incoming messages from Amazon.com were intercepted, copied and stored before they were delivered to the members’ e-mail. Each time the operation was performed, the messages existed in the RAM or on hard disks or both within Interloc’s computer systems. The issue before the 1st Circuit was whether there was an ‘intercept’ of a communication within the meaning of the Wiretap Act. The Electronic Communications Privacy Act (“ECPA”) is divided into Title I, referred to as the “Wiretap Act”, 18 U.S.C. §§ 2510 – 2522 and Title II, commonly known as the “Stored Communications Act”, 18 U.S.C. §§ 2701 - 2711.
