About HA configuration in Fortimail Transparent

[kou_kitani]

Hi.

Is it possible to configure HA(Active/Standby) in TP mode with FortiMail?

I attempted to set up, but a loop occurred.

Is there a way to stop the loop?

<Port configuration>

・FortiMail Port1/Port2 is Bridge Member.

・Port 1 is connected to the switch on the FW side, Port 2 is connected to the switch on the mail server side.

・Port 3 is not config and not cable.

・Port 4 connects directly between FortiMail for HA.
