When deploying 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-mail directly to the internal using SMTP or sends e-mail to the
internal in SMTP via a mail relay that is located on the perimeter’s firewall DMZ network.
B.
The DLP Gateway can inspect internal e-mail (e-mail between two users on the internal
network) if the organization’s internal mail server is located in the internal in the internal network
and users are configured to send e-mail 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-mail (e-mail between two users on the internal network) if the
organization’s internal mail server is located on the another network (not the internal network; for
instance the DMZ or a different internal network) add users are configured to send e-mail to this
mail server using SMTP.
