Folks, I need your knowledge on this one coz I'm far to be familiar with SMTP servers.
I have 3 mail server (exchange) and I'd like to implement a redundant path for relaying mails.
Here comes the topology:
The network that links serverA & serverB is high speed.Code:Server A--------------------------------------ServerB - domain.com | | | | | | Server C--------------------------------------|
The network that links serverA to ServerB through C is low bandwidth.
What I would like to do is to configure a backup SMTP route to serverB smth like
domain.com -> Primary ServerB
domain.com -> Backup ServerC
So when ServerB is not IP reachable from ServerA I would like that the serverA relays frames through serverC. (ouf!)
Thanx guys
