I'm a beginner in piranha HA technology. Don't beat me :)
Please help me to start...
I have 2 servers and i need to confirure high available mail relay.
I don't have additional router/node... 
Each server should receive mail (SMTP) and forward it.
Servers configurations should be independent.
But:
I'd like to have single IP address for this system
I'd like to have load balancing.

Is it enought 2 servers to do that I want?
