Fotigate 100A (2.8) How to setup multiple IP address. One for email only.

Hey Everyone,

Needs some help on a issue we are having at the moment. We are using a Fortigate 100A and we have a couple of external IP Address.
At the moment the Fortigate is working perfectly and all internet traffic is routing fine out through the WAN1 interface (x.x.x.100)
The only problem is we have put in a Exchange server and used a spare IP address with it (x.x.x.101).  We are using port fowarding in the Virtual IP tab to forward 25, 80, 443 (OWA, smtp).
At first this was working great but we noticed that the outgoing traffice from the mail server is going out on the .100 ip as this is the external IP address set on the Fortigate.
This is causing many mail flow issues as spammer see this address as invalid.
If there anyway to setup the Fortigate so that the outgoing traffic from the exchange server goes throug the .101 ip address?

Is there prehaps a better method instead of port fowarding, maybe I should use NAT or add another WAN interface?

Thanks in advance.
