body: <p>I am trying to get all message from inbox and parsing it then sending it to another server.</p>
  
  <p>This is my code:</p>
  
  <pre><code>client.listMessages(0, function(err, messages) 
  {
      var parser = new MailParser(self.mailParserOptions);
      messages.forEach(function(message)
      {
         parser.on("end", function(mail) 
        {
          console.log(mail);
        });
        self.client.createMessageStream(message.UID).pipe(parser);
      });
  });
  </code></pre>
  
  <p>this is parsing perfectly but i am getting this error </p>
