I can imagine several, and they involve running MTAs in disposable
VMs, containers, etc. behind a front-end that automatically routes
mail to disposable back-end servers that spin up or down as needed.
If nginx supports HaProxy protocol then that would be an option.
Or they could just use HaProxy to begin with.
