title: TYPO3 Powermail Captcha
body: <p>I have Upgrade my TYPO3 from 6.2.x to 7.6.15. Now in Powermail the Captcha Field doesn't work anymore. The Image is shown, but when I fill in the Code I got the Message: "Wrong Captcha". So I dig into the Code and found that in Utility.php from the Captcha Extension no <code>$_SESSION</code> is available. So there will be no Comparison. I include the Captcha Extension in Powermail via Typoscript:</p>
  
  <pre><code>plugin.tx_powermail.settings.setup.captcha.use = captcha
  </code></pre>
  
  <p>My System is:</p>
  
  <ul>
  <li>Powermail 3.13.0</li>
  <li>Captcha 2.0.1</li>
  <li>TYPO3 7.6.15</li>
  </ul>
