Is smartd properly configured to send alerts by email?

Alex Flo asked:

I just configured a Debian server as follows
apt-get install smartmontools
vi /etc/default/smartmontools – and here uncommented these 2 lines
# uncomment to start smartd on system startup
# uncomment to pass additional options to smartd on startup

Then I edited /etc/smartd.conf and uncommented only this line
DEVICESCAN -S on -o on -a -m -s (S/../.././02|L/../../6/03)

I was wondering if this is enough for the system to send me an alert message when something goes wrong and/or if there is a way to simulate a problem and see if smartd sends me warnings by email.

My answer:

You can test the configuration by adding -M test to the line that begins with DEVICESCAN, immediately after that keyword. The next time you restart smartd, it will send out an email notification.
