PIX 515 NAT/PAT question

I am using a PIX 515. I only have 1 public IP address from my ISP that is the outside ip address of the PIX. We are installing a mail server on the inside of the PIX. I want all port 25 traffic that comes to the PIX outside IP address to go to the Exchange server on the inside.I can only find configuration guides for a static nat seniro...I can do this on a router but so far I cannot find what I am looking for.

static (inside, outside) tcp interface smtp 192.168.0.15 smtp netmask 255.255.255.255

given that your exchange server is 192.168.0.15.

you will need to have an mx record set up with the outside ip of your firewall to receive email

I had to add a ACL to get this to work. Am I thinking router world or is this the way to do it?
