Gateway mode

In Gateway mode, the FortiMail unit protects your email server by scanning the SMTP traffic 

for viruses and spam messages as it passes through the FortiMail unit.

You can configure your firewall or DNS server to ensure that incoming SMTP traffic goes 
through the FortiMail unit before reaching the email server. Optionally, you can configure the 
email server to use the FortiMail unit as the relay server for outgoing SMTP traffic.

The FortiMail unit integrates into your existing network with only minor changes to your 

network configuration.

Transparent mode

In Transparent mode, the FortiMail unit protects your email server by scanning the SMTP traf-

fic for viruses and spam messages as it passes through the FortiMail unit.

The FortiMail unit provides seamless integration into existing networks. You can place the 

FortiMail unit in front of the existing email server without any configuration changes to the 
existing network topology, for filtering email messages. This means that all of the FortiMail 

interfaces are on the same IP subnet and appears to other devices as a bridge. Alternatively, 

you can configure the FortiMail unit as a combination of a bridge and a router by assigning 

IP addresses to some of its interfaces. In this situation, the interfaces can be on different 
subnets.
