Block all IP's using OUTBOUND Port 25 apart from one

Hello,
This is entirely possilble on any box. This is simple 1:1 NAT translation. Normally you expose the internet to translate a port to and internal port on your server
ie. External Network(0.0.0.0) -> 192.168.1.1:25
All you need to do is choose the set of external IP address you do want to allow.
Optionally you can set up the firewall as above and use your SMTP server to limit connections based on IP and subnet.
It would be helpful to know what firebox you are working with? And what SMTP server?
Thanks
