Hi Firdausi,

will disabling SPF checks on the FortiMail not temporarily solve that problem?

It will be helpful to understand your mail flow as SPF is done from a mail server against received/inbound mail and if the record is not valid, SPF will fail with the configured actions.

Lasting solutions are to instruct the senders DNS service to have proper SPF records.

In other words, the problem is not your FortiMail or mail server config, but the senders DNS service.

Best regards,

Markus
