Compute Engine 上的 Nodemailer Sendgrid

Question

我试图从我的计算引擎实例发送电子邮件，但没有任何反应（没有错误消息）。当我从本地电脑发送邮件时，我收到了电子邮件。

var nodemailer = require('nodemailer');
var smtpTransport = require('nodemailer-smtp-transport');

var options = {};
var transporter = nodemailer.createTransport(smtpTransport({
    service: 'SendGrid',
    auth: {
        user: 'username',
        pass: 'password'
    }
}));
module.exports = {
    sendmailto : sendmailto
}

function sendmailto(emailfrom,emailto, message){

    var mailOptions = {
        from: emailfrom, // sender address
        to: emailto, // list of receivers
        subject: 'Monitoring', // Subject line
        text: message, // plaintext body
        html: '<b>Monitoring</b>' +
        '<p> '+message+'<p>' // html body
    };

  transporter.sendMail(mailOptions, function(error, info){
      if(error){
          return console.log(error);
      }else{
          console.log('Message send: ', + info.response);
      }

    });
};

我发现原因是我自己:) 服务“Sendgrid 用作标准端口 25 但不适用于计算引擎，因此我需要添加端口 2525。

var transporter = nodemailer.createTransport(smtpTransport({
    service: 'SendGrid',
    port: '2525',
    auth: {
        user: 'username',
        pass: 'password'
    }
}));
