The constant HTTP_HOST was not found. Maybe you did not declare it correctly or list all dependencies?

            $this->_SMTP->sendMail(is_null($this->_envelope_from)?$this->_sender_email_address:$this->_envelope_from, $this->_recipients, $this->_body);

$this->_recipients of type array is incompatible with the type string expected by parameter $to of SMTP::sendMail().
