Reply-to options

Hi there!

Thank you for the amazing plugin!

Because of this message from Amazons SES, I set up subdomains and addresses for marketing and transactional emails. Those email addresses (on subdomain) are send-only. No emails can be received there.

I am trying to figure out how to send emails FROM those addresses (with subdomain), but have the Reply-to address something like [email protected].

Could you please give me a pointer?

What I have tried so far:

Add the following snippet to functions.php:

/**
 * START of Change reply email address
 */

add_filter( 'woocommerce_email_headers', 'change_reply_to_email_address', 10, 3 );
function change_reply_to_email_address( $header, $email_id, $order ) {

    // HERE below set the name and the email address
    $reply_to_name  = '[REDACTED]';
    $reply_to_email = '[REDACTED]';

    // Get the WC_Email instance Object
    $email = new WC_Email($email_id);

    $header  = "Content-Type: " . $email->get_content_type() . "\r\n";
    $header .= 'Reply-to: ' . $reply_to_name . ' <' . $reply_to_email . ">\r\n";

    return $header;
}
/**
 * END OF Change reply email address
 */

However, for starters this only affects WooCommerce emails, not ALL emails (via different plugins).

Would you consider implementing a Reply-to address per Connection? That way I could route, for example, all transactional emails through one Amazon SES Connection (using a particular subdomain.domain.tld), and always have those emails have a specific Reply-to address?

Or are there other solutions for this that I am not thinking of?

Thank you very much for your time and reply!
