从Bluemix发送电子邮件失败

Question

我们开发了几个使用SendGrid发送电子邮件的Bluemix中托管的应用程序。自上周以来，所有这些应用程序在没有任何更改后都开始失败。

事实证明，Bluemix开始超时请求SendGrid。我们认为这是SendGrid的问题，所以我们用亚马逊SES取代了服务，令我们沮丧的是，我们开始得到完全相同的错误。

这里是日志的样子：

我们整理了这篇简单的NodeJS应用程序，让我们的错误，看看是否有人看到了什么问题，或者试图出来，并让我们知道是否这实际上是失败在不同的Bluemix帐户：

app.js

var express = require("express"), 
    app = express(); 

var port = process.env.VCAP_APP_PORT || 8080; 
var nodemailer = require("nodemailer"); 

app.use(express.static(__dirname + '/public')); 

app.get("/", function (request, response) { 
    var smtpTransport = nodemailer.createTransport("SMTP",{ 
     host: 'smtp.sendgrid.net', 
     port: 25, 
     auth: { 
      user: "user", 
      pass: "password" 
     } 
    }); 

    var mail = { 
     from: "noreply@ibm.com", 
     to: "user@companyXYZ.com", 
     subject: "Send Email Using Node.js", 
     text: "Node.js send email test", 
     html: "<b>Node.js send email test</b>" 
    }; 

    smtpTransport.sendMail(mail, function(error, resp){ 
     if(error){ 
      console.log(error); 
      response.write(error); 
     } 
     else{ 
      console.log("Message sent: " + resp.message); 
      response.write("Message sent: " + resp.message); 
     } 

     smtpTransport.close(); 

     response.end(); 
    }); 

}); 

app.listen(port);

端口587应该工作。参考：http://blog.mailgun.com/25-465-587-what-port-should-i-use/

你试过吗？请 https://github.com/sendgrid/smtpapi-nodejs/blob/master/examples/example.js

// Use nodemailer to send the email 
var settings = { 
    host: "smtp.sendgrid.net", 
    port: parseInt(587, 10), 
    requiresAuth: true, 
    auth: { 
     user: process.env.SENDGRID_USERNAME, 
     pass: process.env.SENDGRID_PASSWORD 
     } 
    };
