title: Gmail can't receive html email with hyperlink
body: <p>I have to send email to any email account. I have written this code:</p>
  
  <pre><code>$sender = "Me";
  $from = "me@domain.com";
  $recipient = 'somebody@gmail.com';
  $message = "
  &lt;!DOCTYPE html&gt;
  &lt;head&gt;
  &lt;title&gt;Title&lt;/title&gt;
  &lt;/head&gt;
  &lt;body&gt;
  &lt;p&gt;&lt;a href=\"http://www.something.net/verification.php?key=".$code."\"&gt;Click here&lt;/a&gt;&lt;/p&gt;
  &lt;/body&gt;
  &lt;/html&gt;
  ";
  $subject = "subject";
  $headers   = array();
  $headers[] = "MIME-Version: 1.0";
  $headers[] = "Content-type: text/html; charset=iso-8859-1";
  $headers[] = "From: &lt;".$from."&gt;";
  $headers[] = "X-Mailer: PHP/".phpversion();
  mail($recipient, $subject, $message, implode("\r\n", $headers));
  </code></pre>
  
  <p>My problem is, that if I send this message to a gmail account, the reciever doesnt get it. If I miss the hyperlink, or I just miss the '/' from the hyperlink, it works and I get the email.</p>
  
  <p>I dont undarstend why? Something is missing from my code? </p>
  
  <p>If I send this message to another domain, not gmail, it works fine. Just gmail doesnt show me the email with hyperlinks. Whats wrong? Any idea?</p>
