"Send a copy of the receipt to this email:" not working

To be precise, it should be send as Bcc. The code looks correct at: http://cgit.drupalcode.org/commerce/tree/modules/order/src/EventSubscrib... (lines 115-117)

You should debug into that lines and have a look, if the header is really not set

Can you please follow up to #2? We have the following test which asserts the Bcc field is populated

  /**
   * Tests the BCC functionality.
   */
  public function testOrderReceiptBcc() {
    $order_type = OrderType::load('default');
    $order_type->setReceiptBcc('bcc@example.com');
    $order_type->save();

    $transition = $this->order->getState()->getTransitions();
    $this->order->getState()->applyTransition($transition['place']);
    $this->order->save();

    $mails = $this->getMails();
    $this->assertEquals(1, count($mails));

    $the_email = reset($mails);
    $this->assertEquals('bcc@example.com', $the_email['headers']['Bcc']);
  }

@Mediengenosse, what was your fix? Mine is not sending a copy to that email address from the settings, either.

@hockey2112 I second that. I'm not having any luck sending copies of receipts either.

I also encountered such problem, in my case, it was "Swift Mailer" problem. Here is the solution: #2892104: Add support for CC and BCC headers it's wrong conclusion, please ignore it
