How dows the mail spam function works?
does it works at all?

I dont receive any mail on my notify mailbox for the function in the postman:

Is there any explanation how it should work?

// Send mail to admin when someone posts a new spam word
    public function MailReportSpam($data)
    {
        $job_title = BASE_URL . 'job/' . $data['id'] . '/' . $data['url_title'] . '/';
        $subject = '[SPAM on ' . SITE_NAME . '] ' . $job_title;
        $msg .= "Following ad was reported as false/spam:\n--\n\n";
        $msg .= $job_title;
        $msg .= "\n\n" . $data['title'] . " at " . $data['company'];
        $msg .= "\n\n" . $data['description'];
        $msg .= "\n\n--- \n Published by: " . $data['poster_email'];
        $msg .= "\n---\nEdit: " . BASE_URL . "post/" . $data['id'] . "/" . $data['auth'] . "/";
        $msg .= "\nDeactivate: " . BASE_URL . "deactivate/" . $data['id'] . "/" . $data['auth'] . "/";
        $msg .= "\n---\nIP: " . $_SERVER['REMOTE_ADDR'];
        $msg .= "\nDate: " . $data['created_on'];
       
        mail(NOTIFY_EMAIL, $subject, $msg, "From: " . SITE_NAME . " <" . NOTIFY_EMAIL . ">");
    }
