I have a client that has a need for automatic failover of send connectors. The client currently has a send connector that resolves to a smart host and sends to the internet. I need to setup a way that if the smarthost goes down the mail will automatically route directly to the internet. I have attempted to setup another send connector with a higher cost and I have it set to route via MX, But when I simulate failure of the smarthost and send messages they get stuck in the smarthost queue.
I am looking for options to resolve this request. Thanks in advance for your help!
