Well I think we're narrowing down the problem here. The answer to that
question is NO!
And interestingly NEITHER DOES ROOT!

It seems that fixing /etc/aliases now allows me to get SYSTEM messages
(e.g. logwatch, fail2ban stops/starts etc.) but NOT cron output.

So the problem seems to be that cron is somehow not configured to send
mail. Could that be right? If so, where do I start in trying to fix
it?

How do I do that?
