title: mailto crontab doesn't work
body: <p>I'm running a script on my mybookworld(NAS) via crontab every day. And it would be nice if it could send me everyday an email report with the output of the script.</p>
  
  <p>So I looked at MAILTO in crontabs, but it doesn't send me anything at all. The script ran correctly at the right time, but there was no email.
  This is my crontab:</p>
  
  <pre><code>~ # crontab -l
  MAILTO=x.y@googlemail.com
  
  0 0 * * * python /root/erepCrawler/src/main.py
  </code></pre>
  
  <p>I've written a "smaller" crontab for testing reasons:</p>
  
  <pre><code>MAILTO=x.y@googlemail.com
  * * * * * echo "blaah"
  </code></pre>
  
  <p>This should send me every minute an email with "blaah" as the body. If I'm wrong please correct me.</p>
  
  <p>Is there another package needed for sending mails with crontab? sendmail is installed in /opt/sbin/sendmail.</p>
