FortiMail uses RADIUS accounting records to combat spam and viruses originating from your network, reducing the likelihood that your public IP addresses will be blacklisted.
- Configure the FortiMail unit as an auxiliary RADIUS server on your RADIUS server.
- Ensure it sends the Calling-Station-ID and Framed-IP-Address attributes to the FortiMail unit.
- Determine whether your RADIUS server sends the Framed-IP-Address attribute value in network order (for example, 192.168.1.10) or host order (for example, 10.1.168.192).
- Verify that routing and firewall policies permit RADIUS accounting records to reach the FortiMail unit.
