Yes, if you have a support contract with Fortinet run this through them as a call.
If you do not have one I would get one.

I would recommend using Mimecast and then to Nat that through your firewall securely.

Otherwise you can make a bad choice and send and receive internet directly over the internet through your ISP smtp server.

The second solution is pretty bad, the only reason I am suggesting it is because other people will do so just to get points.

Also

Natting on Fortigate device https://forum.fortinet.com/tm.aspx?m=136309

Also just to be clear the Fortigate will protect your exchange or mail server externally internet facing wise, not internally, if you want an internal firewall use a 3rd party product or windows firewall.

Hello,

To access your SMTP/IMAP/Exchange service from internet, you have to create the port forwarding rule on FortiGate. Refer the below article for the step by step instruction,
http://cookbook.fortinet.com/using-virtual-ips-configure-port-forwarding-54/

To protect your mail server from internet, I would recommend you to enable DOS protection, AV, IPS and AntiSpam profile.
