title: Crontab 'No MTA installed, discarding output'
body: <p>Crontab does not write into the specified logfile. Is there any syntax error in my command?</p>
  
  <pre><code>*/5 * * * * (cd /some/dir &amp;&amp; python -m some.python.module)  &gt;&gt; /dir/with/the/logfile.log 2&gt;&amp;1
  </code></pre>

  <pre><code>0 3 * * * (cmd1;  cmd2)  &gt;&gt; /some/log/file 2&gt;&amp;1
  </code></pre>
  
  <p>is suggested. When I execute the two commands by hand they work perfectly fine and I can see the output on <code>stdout</code>.</p>
