Install mailutils with:

    sudo apt-get install mailutils

Set up the cronjob with:

    crontab -e

To send at 10 mins past the hour add:

    10 * * * * sh /path/to/script

**If you'll be emailing the same domain that your mailname is set to:**

Navigate to `/etc/postfix/`

    sudo vi main.cf

Find line beginning `mydestination`, it should say something like:

    mydestination =  ubuntu, localhost.localdomain, localhost

Crucially it shouldn't contain your mailname or references to it, or your emails will be sent internally on the server.
