How to send a letter to the admin with a substitute e-mail of the sender for the e-mail of the buyer?

Question

opencart

Good afternoon, I'm struggling with such a task. How to implement so that letters to the admin about orders come with the substitution of the sender's email for the buyer's email. That is, what would a person order with email - [email protected] and it was he who was the sender of the letter to the admin, and not the store's mail. OpenCart 3
Found these lines in mail/order.php

$this->load->model('setting/setting');
    
    $from = $this->model_setting_setting->getSettingValue('config_email', $order_info['store_id']);
    
    if (!$from) {
      $from = $this->config->get('config_email');
    }
    
    $mail = new Mail($this->config->get('config_mail_engine'));
    $mail->parameter = $this->config->get('config_mail_parameter');
    $mail->smtp_hostname = $this->config->get('config_mail_smtp_hostname');
    $mail->smtp_username = $this->config->get('config_mail_smtp_username');
    $mail->smtp_password = html_entity_decode($this->config->get('config_mail_smtp_password'), ENT_QUOTES, 'UTF-8');
    $mail->smtp_port = $this->config->get('config_mail_smtp_port');
    $mail->smtp_timeout = $this->config->get('config_mail_smtp_timeout');

    $mail->setTo($order_info['email']);
    $mail->setFrom($from);
    $mail->setSender(html_entity_decode($order_info['store_name'], ENT_QUOTES, 'UTF-8'));
    $mail->setSubject(html_entity_decode(sprintf($language->get('text_subject'), $order_info['store_name'], $order_info['order_id']), ENT_QUOTES, 'UTF-8'));
    $mail->setHtml($this->load->view('mail/order_add', $data));
    $mail->send();
  }

Here, as I understand it, an e-mail is formed for sending messages ( 'config_email') but I don’t fully understand how to change it to the user’s e-mail variable ($order_info['email']).
I would appreciate any help, thanks in advance.

Answer 1

- change here $mail->setFrom( $from );
but keep in mind that the mail service may not let such letters through in some cases, considering them to be spam
