title: PHPMailer AltBody is not working
body: <p>PHPMailer Version 5.2.7</p>
  
  <pre class="lang-php prettyprint-override"><code>$mailerObject = new PHPMailer;
  $mailerObject-&gt;CharSet = 'UTF-8';
  $mailerObject-&gt;IsSMTP(); 
  $mailerObject-&gt;Host = 'dsfdf.sdfsdf.com';
  $mailerObject-&gt;SMTPAuth = TRUE;  
  $mailerObject-&gt;Username = 'dfgdfg';
  $mailerObject-&gt;Password = 'dfgdfgdfg'; 
  $mailerObject-&gt;SMTPSecure = 'tls';
  $mailerObject-&gt;WordWrap = 60;
  $mailerObject-&gt;From = 'alex@test.de';
  $mailerObject-&gt;FromName = 'test.de';
  $mailerObject-&gt;AltBody = $bodyTextTemp;
  $mailerObject-&gt;MsgHTML($bodyHtmlTemp);
  </code></pre>
  
  <p>I am sending an HTML-Mail and an Text-Mail. In Thunderbird in HTML-Mode HTML is correctly shown. In Text-Mode you cant see the Text-Content ($bodyTextTemp), but the HTML-Content ($bodyHtmlTemp) where all HTML-Tags were removed (looks very ugly...).</p>
  
  <p>Looking to the Mail-source, I can see that the AltBody wasnt send.</p>
  
  <p>Why PHPMail dont accept my AltBody? </p>
