title: Email goes to spam because of "HTML Obfuscation"
body: <p>According to the spam-test available at <a href="http://www.contactology.com/check_mqs.php" rel="nofollow">this link</a> -- The automated, "Thank you for signing up" emails are going into the spam folder because : </p>
  
  <pre><code>SPAM: BODY: Message is 10% to 20% HTML obfuscation (-32)
  </code></pre>
  
  <p>However, I can't find anything that explains what that means - </p>
  
  <p>I'm using SwiftMailer, and this is the relevant code that I use to set the headers / add the HTML part : </p>
  
  <p>[...]
      $body_txt = strip_tags($body); 
      $message = Swift_Message::newInstance();</p>
  
  <pre><code>$typeone = $message -&gt; getHeaders() -&gt; get('MIME-Version');
  $typeone -&gt; setValue('1.0');
  
  $typetwo = $message -&gt; getHeaders() -&gt; get('Content-Type');
  $typetwo -&gt; setValue('text/html');
  $typetwo -&gt; setParameter('charset', 'utf-8');
  
  $message -&gt; setSubject($subject)
           -&gt; setFrom(array("courier@".TRIMMED_DOMAIN =&gt; HUMAN_READABLE_URL))  
           -&gt; setTo($to)
           -&gt; setBody($body_txt)
           -&gt; addPart($body, 'text/html');
  $transport = Swift_SmtpTransport::newInstance(TRIMMED_URL, 25)
                  -&gt; setUsername("courier@".TRIMMMED_URL)
                  -&gt; setPassword(MAILER_PASSWORD); 
  $mailer = Swift_Mailer::newInstance($transport);
  $result = $mailer -&gt; send($message);
  </code></pre>
  
  <p>And the email, itself, with lots of text omitted:
  (Perhaps we are using too much HTML?) </p>
  
  <pre><code>&lt;!doctype html&gt;

  <p>So if anyone can give me any insight at all on what is triggering this <code>HTML obfuscation</code> flag, then I would greatly appreciate it. </p>
