I have 4 VPS servers, my plan is to use one of these VPS servers as a load balancer which sends mail received by it from another server to other 3 VPS (smtp) clients who will relay mail to the outside network.
The idea is:
-> VPS2 VPS1 -> VPS3 -> VPS4
I want Postfix to be used as an MTA in this configuration. Can anybody help me out in this?
All servers have CentOS 5 as their OS.
