I have a multi-server environment.. namely smtp1 10.0.0.3 and smtp2 10.0.0.4 both listening on port 25 for in/out smtp messages. Mailbox is at 10.0.0.2.
To achieve this thing, only for outgoing.. I had to specify smtp1 only for outgoing msgs and smtp2 for incoming.
How can I make both of these servers to listen for in/out concurrently thus giving some redundancy/load balance to the system? Any idea?
Theoretically, I am thinking of the split NIC or the virtual NIC thing, so that i can specify [incoming ip]:smtp and [outgoing ip]:smtp for each servers ; but is this method really works? Anybody have done it? I am maintaining a production system so downtime is very limited. Need some expert/tested help/opinion on this.
Anyways, very appreciate what you guys been discussing on this thread! So cool... Thanks..
