I feld exactly the same when I saw both mail servers where in the same
subnet. No point in doing that.

Jussi should run 2 identical setups in 2 hosts as MX with same priority
if redundancy is desired. Of course, having them as VMs on the same
hosts limits the redundancy quite a bit as the host is the single point
of failure here.
