In the case of there is no Edge T server in thenetwork, just a couple of H-T , how do they replicate their Databases (mail.que)?
let say a message is coming from outside:
in case we have in our network
CAS1 and Hub1 on the same server and CAS2 and Hub2 on the other serve, adn MB1 and MB2 in 2 other different servers ( All makes 4 servers)
my question is how do Hub replicates their DB in case one of them dies?
