Installation of the I.C.E. Box
The I.C.E. Box is a secure network appliance that can be placed anywhere in a network infrastructure so long as the email flow runs through the I.C.E. Box before arriving at the mail server (MTA). Below is just one typical architecture. The I.C.E. Box can also be placed in the DMZ. In larger deployments, the I.C.E. Box can be placed in series in front of existing anti-spam systems to further ease installation.
The I.C.E. Box is installed "logically" between the Internet and one or more email servers (e.g. MS Exchange or Lotus Notes). The corporate MX (Mail eXchange) record in DNS is set to point to the I.C.E. Box, allowing all email from the Internet to be routed to the I.C.E. Box. The I.C.E. Box receives the messages, processing them through a series of email security services, eliminating the unwanted messages, and forwarding the remaining email to the server(s) for delivery.
