Nodemailer DNS配置似乎不起作用

问：

需要帮助在我的nodeJS项目上的nodemailer电子邮件消息配置上设置DNS信息 我尝试设置DSN收件人被忽略，并且从未发送DSN。

示例代码：

const nodemailer = require("nodemailer");

let transporter = nodemailer.createTransport({
    host: "localhost",
    port: 1025,
    secure: false, // upgrade later with STARTTLS
});
transporter.sendMail({
    from: '[email protected]',
    to: '[email protected]',
    subject: 'Test Receipt',
    text: 'Did you get a failure?',
    envelope: {
    dsn: {
        id: 'messageId',
        return: 'FULL',
        notify: 'success',
        recipient: '[email protected]',
    },
    },
}, (err, info) => {
    console.log(info.envelope);
    console.log(info.messageId);
});
