When deploying a dedicated DLP Gateway behind a perimeter firewall on an interface leading to the internal network (there is only one internal network):
A.
The DLP Gateway can inspect SMTP traffic if a MS Exchange server is located on the internal network, and it either sends e-mails directly to the Internet using SMTP or sends e-mails to the Internet in SMTP via a mail relay that is located on the perimeter’s firewall DMZ network.
B.
The DLP Gateway can inspect internal e-mails (e-mails between two users on the internal network) if the organization’s internal mail server is located in the internal network and users are configured to send e-mails to this mail server using SMTP.
C.
User’s HTTPS and FTP traffic can be inspected by the R71 DLP Gateway.
D.
The DLP Gateway can inspect e-mails (e-mails between two users on an internal or external network) if the organization’s internal mail server is located on another network (not the internal network; for instance the DMZ or a different internal network) and users are configured to send e- mails to this mail server using SMTP.
