Is it possible to set up MIAB across multiple servers, like a server group, then use load balancing for incoming and outgoing emails? Or is this only meant to be on one server. I am using MIAB to service many clients in a web application as they will be sending lots of data to us, and we will parse that data and load it into our databases. My concern is that one server alone can not handle all of these requests. I am sure this use case comes up often, can you direct me to how I would love it?
