Fault Tolerance
For mails to be delivered in a specific order, preferences of Inbound Servers should be set differently based on your desired priority.
The lower the number, the higher the priority. -
Load Balancing
For mails to be delivered in no particular order, preferences of Inbound Servers should be set the same.
Preferences are numbers from 1-100.
