Generating SPF record

Hi,

I'm trying to generated a SPF record to be put into our GoDaddy hosting for blocking off the impersonated emails.

After reading some examples and articles online, now I'm just lost.

We have FortiMail running in the gateway mode and is the only hosted MX record on GoDaddy.

FortiMail --> fortimail.mycompany.com

and we have our own exchange server.

Exchange --> mail.mycompany.com

so is my SPF record just like the screenshot below?

Any advice and help is appreciated.

Cheers,
