In EOP "Outbound Connector" when adding
"multiple" smart-host entries, I know that the first smart-host to deliver messages to is chosen at random from the list, following that, the connector uses round-robin load balancing to distribute messages among the smart-host
entries.
My question is: what happens if one of the smart-hosts gone off-line for hours, will the EOP deliver emails to it and the senders would receive delivery errors?, or the EOP will sense that it's down and stop delivering emails through it?
