Hello all.
I have the following situation. A colleagues installed a spam block (Norton something) and he put two ip's on itsinterfaces. 192.168.2.20 and 192.68.2.21. One will be used to receive and one to send mail but both on port 25. They use a sinlge real IP 175.75.67.32. I am using a 5540 ASA with 8.2 IOS.
I am pretty sure this cannot happen but i got some advice to NAT the outgoing IP/Port and then PAT the incoming port to both IP's and it will work. I tried to do it with no success. I know that ASA 8.4 changes everything in NAT/PAT but is there any way with the newer OS my setup can work or not???
Thanks very much in advance for your help.

ASA 8.4:
receive mail:
nat (inside,outside) source static obj-192.68.2.20 obj-175.75.67.32 service src25 src25
send mail:
nat (inside,outside) source dynamic obj-192.68.2.21 obj-175.75.67.32 service dst25 dst25
