Magento 2 - All sales emails to same address (no emails to customer)?

Question

When sending order confirmations, I wish to have them all go to a specified email address and disable them going to the customer.

Please note, this is for internal use, where everything is free and no legal requirements to offer invoices/etc. I need to send data for the order and customer via this order email, formatted so that it can be captured by another system.

I found within Magento/vendor/magento/module-sales/Model/Order.php on line 2501:

/**
 * Returns customer_email
 *
 * @return string
 */
public function getCustomerEmail()
{
    return $this->getData(OrderInterface::CUSTOMER_EMAIL);
}

and then again on line 4045:

/**
 * {@inheritdoc}
 */
public function setCustomerEmail($customerEmail)
{
    return $this->setData(OrderInterface::CUSTOMER_EMAIL, $customerEmail);
}

Editing this works, in that I can redirect all emails to a static address (example@domain.com) but it also replaces the customer's email as it appears in the order to the same address (example@domain.com). I still need to have the CUSTOMER_EMAIL value = the customer's email as I need to send that within the email as part of the email body.

Which is the right file to edit where the sending of the email is executed so I can change the address there?

Thank you very much in advance!

Answer 1

AFAIK email address set in here

vendor/magento/module-sales/Model/Order/Email/Sender.php 

prepareTemplate() method

But you can not create prefrence of this class as its abstract.

So what you can do is create prefrence of this clas vendor/magento/module-sales/Model/Order/Email/Sender/OrderSender.php

and with in send() method wrap your code before and after this code $this->checkAndSend($order)

what You can so is

$orignalCustomerAddr = $order->getCustomerEmail();
$order->setCustomerEmail($yourEmailAddr); 
//after $this->checkAndSend($order) this line below code
$order->setCustomerEmail($orignalCustomerAddr);  

Update as per OP requirement

For using $originalCustomerAddr in template you can add one extra array result in prepareTemplate method.

So just add one extra variable like this in $transport result set

    $transport = [
        'order' => $order,
        'billing' => $order->getBillingAddress(),
        'payment_html' => $this->getPaymentHtml($order),
        'store' => $order->getStore(),
        'formattedShippingAddress' => $this->getFormattedShippingAddress($order),
        'formattedBillingAddress' => $this->getFormattedBillingAddress($order),
        'orignalEmail'=> $orignalEmail
    ];

And in email template you can use this variable as orignalEmail
