Hello all, With what (I hope) will be my final update on this issue.
This machine is a simple home server. It runs headless and is on 24/7. I
an in the habit running yum update once per month and only then
rebooting (and only then because the yum update usually brings down a
new kernel). I long ago left the Windows world where a reboot was
required for - well everything really. Since this is a new install
however I had rebooted a few more times than normal, but the last one
was a few days ago.
Last night (more in desperation than anything else) I rebooted.
Today - Cron emails!
I am very sorry for wasting everyone's time. I have no idea what the
problem was or why a reboot solved it - some environment variable
perhaps?
Anyway I am now a happy bunny and, as always, grateful for the friendly
and helpful support given here.
Thanks again.
Mark
