我们目前正在使用Nodemailer发送和接收公司内部的电子邮件。我们最近已经超过了我们的日常SMTP中继，这意味着一些电子邮件将不会发送。我被要求检查有多少电子邮件，我们的“无回复”电子邮件发送每天的基础上，看看是否有一个原因，我们正在超过这些限制。任何建议和想法将不胜感激。
注意：我是Nodemailer的新手，对它了解不多。
我试着破译现有的代码，但没有多大意义。我想我应该创建一个计数器，每当有来自该电子邮件的sendmail（）请求时，该计数器就会递增，但我不知道如何发送说明该值的每日报告。
这是我们的server.js文件中的内容。注意：出于保密目的，已修改了一些名称

var smtpTransport = nodemailer.createTransport({
    service: env.EMAIL.SERVICE,
    host: env.EMAIL.HOST,
    auth: {
        user:env.EMAIL.AUTH.USER,
        pass:env.EMAIL.AUTH.PASS
    }
});

app.get('*', function (request, response) {
    if (request.get('x-auth')) console.log("x-auth: ", request.get('xauth'));
    const proto = request.get('X-Forwarded-Proto');
    if (proto) {
        if (proto === 'http') response.redirect(301,"https://myapplication.net".concat(request.url));
    }
    response.sendFile(path.resolve(__dirname, '../', 'public', 'index.html'))
    if ((request.url).substring(0, 5) == "/send") {
        var mailOptions = {
            to: request.query.to,
            bcc: request.query.bcc,
            subject: request.query.subject,
            text: request.query.text
        }
        //console.log(mailOptions); Read up on NodeMailer for details.
        smtpTransport.sendMail({  //email options
            from: " <noreply@someemail.com>", // sender address.  Must be the same as authenticated user if using Gmail.
            to: mailOptions.to, 
            bcc: " <noreply@someemail.com>",
            subject: mailOptions.subject, // subject
            html: mailOptions.text // body
        }, function (error, response) {  //callback
            if (error) {
                //console.log(error);
            } else {
                //console.log("Message sent: " + response.message);
            }

            smtpTransport.close(); // shut down the connection pool, no more messages.  Comment this line out to continue sending emails.
        });
    }

});

我猜这就是它的名字

var to = this.props.msgList.EmailTo;

var text = `<div>Hello from no-reply</div>`;

$.get("/send", { to: to, subject: 'Response Rates', text: text },function (data) { });
