comment Emails from my server are often being blocked as spam
The forward and reverse DNS should match the server, not the sending domain, otherwise you couldn't host more than one domain on one IP address. But this is a likely reason though, PTR record not present.

comment How do I tell what process is causing kswapd to be in use?
@Zaz I am sure that kswapd when using swap leads to high apparent CPU through IOWAIT. It looks like you are having a different problem however.

comment How do I tell what process is causing kswapd to be in use?
@Zaz It isn't so much that it is using CPU processing power to do swapping, it is that the CPU is 100% used due to IOWAIT. Each time memory needs to be swapped in from disk, the CPU has to sit there and wait for it - IOWAIT, and isn't doing anything else (on average).

comment how can I present a network diagram on the building that has 3 floors
Often with network diagrams, problems arise when you try to attempt to do a logical and physical design in a single diagram. It is usually easier to both create and read a network layout where these are two separate diagrams. Do one diagram with your vlan setup with the departmental separation, and another with your hardware setup across the floors.

comment Hardware Acceleration for MD RAID?
@NathanC Feasibility does not imply a product exists. Generally it is taken to mean the opposite.

comment Hardware Acceleration for MD RAID?
@Iain I think you may have misunderstood the question. It is simply asking if the RAID6 computation in MD can be accelerated in hardware. There is no part of this question that asks whether MD RAID or hardware raid is a "better" option in any scenario.

comment Exim Autoreply router doesn't work for aliases
@Kondybas Is there something else in the preceding routers I should be looking for? Everything else in the routers is vanilla Debian if that is useful.
