[FortiMail] The mail message logs are showing the incorrect Client IP

Hi,

 

We have FortiMail in our setup which was installed by a 3rd party. In the message logs, the Client IP is showing our Router's private IP. Is there a setting in FortiMail to use the originating IP of the email?

 

Below are screenshots of the logs and a sample of one of the spam message headers.

 

Thank you,

Hello,

humm, that's a misconfiguration in the router; not directly related with fortimail.

You shouldn't see 192.168.20.1 as FEAS-CLIENT-IP header in such emails.

It is likely the router/firewall policy be NATting incoming traffic.

If your router is a FortiGate, check incoming firewall policy used to publish your fortimail. It shouldn't be NATted

Thanks for that abelio. It was a router issue and has been sorted out.
