Do you have an Address Translation Tab in 4.1?  Can you not create a Static NAT to the Server?

NAT is already defined. SMTP SERVER -> 192.168.0.77 NAT STATIC to 200.250.68.131

and route 200.250.68.131 to 192.168.0.77.

Mail Server IP = 192.168.0.77

I want to redirect incoming SMTP port 25 to 192.168.0.97 (ChoiceMail Antispam Server) port 25

I'm not exactly sure what the interface looks like in 4.1 but in NG and above it's done like this: Put the new Manual NAT rules above the existing rules and make it only apply to smtp traffic.
