Hi,
Anyone can help me in some configuration guide or links or whitepaper on Content Switch server load balancing for SMTP servers, most of the examples are for WebServer.
Had anyone done lb for incoming tcp 25 connections to VIP to rounrobin bet two SMTP servers with client source ip persistence?

I have SMTP setup with the below basic configuration, This works, however I would like the mail messages after being recieved by the client to be sent to remote servers by their own real ipaddresses, so that the VIP is not a single IP address that may get blacklisted easily. I have about 4 smtp servers. I also need the real client IP addresses to show up in logs.
I have 2x11503's each with 2sfps each uplinking to its own 2960.
Any help?
(ips changed about; requests come in on 192.168.1.230, 10.10.10.x is the mailserver real ip network)
They have the a gateway of 10.10.10.155
