I think you are misunderstanding what the static command does or I misunderstand what you are trying to do.
You have a server at 188.8.131.52.
You have a server at 10.10.10.11 (spam filter)
you have a server at 10.10.10.5 (groupwise).
This statement: static (inside,outside) 184.108.40.206 10.10.10.11 netmask 255.255.255.255 0 0
makes the spam filter server appear to the outside as 220.127.116.11.
If you do not have any server at 18.104.22.168, you can change the static statement above so that the groupwise server appears to to rest of the world as 22.214.171.124, but you cannot do what you are stating in your post.
I am running Software 5.2
I am just having problems figuring out the right command.
Issue is this, I have my Public IP address for my mail server 126.96.36.199
I have my Spam Filter : 10.10.10.11 and Groupwise server 10.10.10.5
