This code seems to be duplicated across your project.

            if (!$attachment instanceof Swift_Image
                || !in_array(self::SMTP_API_NAME, [$attachment->getFilename(), $attachment->getContentType()])
            ) {

            $data['x-smtpapi'] = json_encode($attachment->getBody());
        }
    }
