addHeader() from Zend Mail
I'd like to add specific headers in the Form Submission Email such as Importance. I know Zend has a function addHeader() (http://framework.zend.com/manual/1.12/en/zend.mail.additional-headers.html), but Concrete5 doesn't seem to support it. Or does it?
Can anyone help me out?
$mh->addHeader('X-Priority', '1'); $mh->addHeader('X-MSMail-Priority', 'High'); $mh->addHeader('Importance', 'High');
in core/controllers/blocks/form.php doesn't work.
