Debian install MailUtils needs configuration of Exim

When you first install MailUtils on Debian

apt-get install mailutils

The system will not send emails.

To test it:

echo "This is the body of the email" | mail -s "This is the subject line" myemail@gmail.com

and have a look at the logs:

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.
