This documentation should provide some insight on configuring email alerts in icinga.

The documentation mentions that you must have a working method to send email from the command line. Installing the postfix package will allow access to the sendmail command. This will get you started though to prevent delivery issues you may want to look into a transactional email service like sendgrid which provides a free level of service and route your email via SMTP instead.
