by default I use spool mailing solution for sending newsletter in my web page. But I also need to send email immediately. So I have used this solution
If I send newsletter with Spool everything is fine. But when I use
$mailer = $this->get('instant_mailer');
I receive email with some text prepend at the beginning:
HTTP/1.0 200 OK Cache-Control: no-cache Content-Type: text/html; charset=UTF-8 Date: Fri, 07 Sep 2012 16:19:06 GMT
How to remove this?
