Simplest way is to NAT the public IP to the Private IP across your firewall.

So for example on the public side of the firewall translates
to on the internal side

Depending what services you are running on the Exchange box you could also
consider only exposing port 25.

So only traffic to port 25 is routed to the Internal server.
