Configure failover mode or parallel mode

You can configure relay servers for failover or parallel mode if you have more than one relay servers configured. These options provide additional assurance that the email delivery component of your alerting system is functional.
When you use failover mode or default mode, the primary relay is available. If the primary relay is unavailable then other relays are available.
When you use parallel mode, all the relays are available and the work is distributed among the relays based on the number of connections. This mode can improve performance when one relay does not have the capacity to handle all the work.
