man mdadm
and the software RAID HOWTO
http://www.tldp.org/HOWTO/Software-RAID-HOWTO.html
are worth reading.

Looking at the mdadm.conf you included your OP, you already have a mail
address configured where problem reports shall be sent.
When you installed mdadm a monitoring process should have been set up
automatically. Look for something like "/sbin/mdadm --monitor" in the
output of
ps -ef
if it really is running.

mdadm --monitor --test --scan
Should mail a status report for every RAID device found on the machine
(replace --scan with a device name if you don't want multiple mails).
This way you can check if the mailing of reports really does work.
