BTW, the two servers are virtual machines in one and the same physical box.
What's the point of that? (Genuine question.)
One server here, one across town, or even two separate boxes in a single room -- sure. But in the same box? If the the box is on fire, now you're out both your main and your backup server.
I must be missing something; what is it?
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.
