Yes, that's right. One failure, one email. I'm not in the business
of spam.

Exactly.
It has occurred to me that it could be useful to send mail at startup
if there appear to be any abnormalities, but I think I would prefer
that sort of functionality to be external. A sysdamin might want that
mail are reboot, or every night, or every week, or never. A simple:
grep -s > /dev/nu $magic_pattern /proc/mdstat &&
mail -s "Raid problem on `hostname`" root << END
Possible RAID problem, please check.
`hostname`
`cat /proc/mdstat
END
is all that is needed.

That's quite possible.
Once for Fail
