title: Backup2mail can't send email with database backup..multiple or malformed newlines?
body: <p>Until 18 June I received all days my backup database on Gmail without problems, I had finally found the solution for this. But after 18 June emails with database are stopped. I don't receive neither normal email with only log file txt..nothing I receive now.</p>
  
  <p>I use Backup2mail <a href="http://www.backup2mail.com/" rel="nofollow">http://www.backup2mail.com/</a></p>
  
  <p>PHP Version 5.6.13, Ubuntu Linux 14.04.1</p>
  
  <p>The database backup file is perfectly created on server but it can't send more to Gmail.</p>
  
  <p>I have this error in index.php file of Backup2mail:</p>
  
  <blockquote>
    <p>Warning: mail(): Multiple or malformed newlines found in additional_header in > /srv/users/serverpilot/apps/myappname/public/backuptomail/index.php on line 119
    Database not sent! Please check your mail settings.
    Sent? No</p>
  </blockquote>
  
  <p>On line 119 there is:</p>
  
  <pre><code>if (mail($send_to, $subject, $body, $headers)) {
      $sent = 'Yes';      
      echo ($file_is_db ? 'Backup file' : 'Report') . ' sent to ' . $send_to . '.&lt;br /&gt;';
      if ($file_is_db) {
          if ($delete_backup) {
              unlink($file);
              echo 'Backup file REMOVED from disk.&lt;br /&gt;';
          } else {
              echo 'Backup file LEFT on disk.&lt;br /&gt;';
          }
      }
  } else {
      echo '&lt;span style="color: #f00;"&gt;' . ($file_is_db ? 'Database' : 'Report') . ' not sent! Please check your mail settings.&lt;/span&gt;&lt;br /&gt;';
  }
  
  echo 'Sent? ' . $sent;
  </code></pre>
  
  <p>Where is the problem? :( Maybe from 18 june PHP is upgraded and changed something? I'm not expert.</p>
  
  <p>Thank you in advance</p>
