Route oubound traffing throuhg secondary wan IP

[lebisol]

Hello everyone,
I was just wondering how to get this accomplished...

I have an exchnage server sitting behing a NAT on 1841.
My inbound traffic on port 25 points correctly through NAT and gets delivered without any problems.
However my outbound traffing goes out through default gatway/wan ip and reflects as coming out from the main IP as it should normally.

I was wondering how to route it so that oubound connections on port 25 from specific internal IP are reflected throuhg my secondary wan IP?
eg. 192.168.1.10 tcp 25 ---out--> xxx.xxx.xxx.77
while the the rest of machines
192.168.1.x tcp 25 ---out--> xxx.xxx.xxx.88

Many thanks for your time,
All the best!
