Trigger send email

I'm having problem to send an email to an user when triggers occur.

The alarm is showed in the panel, but no email is send.

mysql> select * from triggers;
+----+-------------------------+-------+
| id | description             | type  |
+----+-------------------------+-------+
|  1 | No Trigger              | alarm |
|  2 | Interface Status Change | alarm |
|  3 | Trigger Test            | alarm |
+----+-------------------------+-------+
3 rows in set (0.00 sec)

mysql> select * from triggers_rules;
+----+------------+-----+----------------+----------+----------+-----------+-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+------+--------+
| id | trigger_id | pos | field          | operator | value    | action_id
