We are trying to make our exchange system as failover as possible
Aside from my DAG configs I have a 2nd send connector( smartHost) to a separate subnet and mail appliance. My 1st connector has a cost of 1 and the second has a cost of 99. If I manually disable the 1st connector mail will flow via the 2nd out to the internet, however if I unplug the lan cable from our mail appliance all the email Qs up on the mail server. can anyone shed light as to why the mail doesn't flow to the 2nd connector when both are enabled but 1st mail appliance is down??
