Description
In some case there is a device in front of a FortiMail which is forwarding all emails to the FortiMail.

If so, there will be issues with SPF checks, since any domain with a hard fail (-all) in their SPF/TXT record will fail since the IP of the incoming device in not in their SPF/TXT records.  

Solution
The only way around this is to either disable SPF checking, white list trusted domains or create a recipient policy for trusted domains with an antispam policy with SPF checking disabled.
