The 3Com Email Firewall is designed to be situated between your mail
servers and the Internet so that there are no direct SMTP (Simple Mail
Transport Protocol) connections between external and internal servers.
The 3Com Email Firewall is installed behind the existing firewall on the
Internal network.
Inbound mail will be forwarded from the Firewall or Router to the 3Com
Email Firewall where it will be scanned, processed, and then sent to your
internal mail server for delivery.
Outbound mail will be sent from your internal mail server to the 3Com
Email Firewall to be scanned, processed, and then delivered to the
destination SMTP server on the Internet.
