apt-get install mailutils

echo "This is the body of the email" | mail -s "This is the subject line"

cat /var/mail/mail

To fix this, it is needed to configure Exim:

dpkg-reconfigure exim4-config

You will be presented with a setup wizard of something like this:

The settings are pretty straight forward but you can just leave them with Internet Site and type your domain. The rest should work with the default settings.
