使用 AWS SMTP 设置 Meteor 电子邮件

Question

此 Meteor 服务器代码尝试从服务器启动时发送电子邮件。
我在阅读 AWS docs 后遵循的步骤是：
1) 验证也在 AWS webMail 上的电子邮件地址。
2) 用于增加发送限制。
3) 创建和接收 SMTP 凭证。

流星 1.4.4.2
电子邮件@1.2.1

//server/main.js

smtp = {
  'username': 'from smtp credentials',
  'password': 'from smtp credentials',
  'host': 'email-smtp.us-east-1.amazonaws.com',
  'port': '465',
  'auth': true
};
process.env.MAIL_URL = 'smtp://' + encodeURIComponent(smtp.username) + ':' + encodeURIComponent(smtp.password) + '@' + encodeURIComponent(smtp.outgoingServer) + ':' + smtp.outgoingPort;

Meteor.startup(() => {

      Email.send({
        to: 'my-aws-verified-email@comp.com',
        subject: 'sending-to-myselft',
        text: 'Just checking if it is working'
      });
});

错误：getaddrinfo ENOTFOUND undefined undefined:587

知道如何让它工作吗？谢谢

编辑
将process.env.MAIL_URL 值更改为：

process.env.MAIL_URL = 'smtp://' + encodeURIComponent(smtp.username) + 
':' + encodeURIComponent(smtp.password) + 
'@' + encodeURIComponent(smtp.host) + 
':' + smtp.auth + ':' + smtp.port;

现在的错误是：

错误：从未收到问候

将端口更改为“587”会产生不同的错误：

错误：邮件命令失败：501 提供的 MAIL FROM 地址无效

您同时解决了两个问题，当您解决其中一个问题时，您并没有明显取得进展，因为您遇到了另一个问题。

对于出站电子邮件，SES 侦听两组端口。

标准端口 587、传统（但错误的）端口 25 和非特权端口 2587 上的 STARTTLS。

标准端口 465 和非特权端口 2465 上的 TLS Wrapper。

这两组的区别在于 SSL (TLS) 的协商方式。使用 STARTTLS，服务器先对话，客户端要求连接切换到加密模式……而使用 TLS Wrapper，连接以 TLS 开始，但客户端先对话，启动 TLS 协商。

显然，根据这些描述，当客户端预期使用 STARTTLS 时使用 TLS Wrapper 端口将导致超时，因为双方都在等待对方通话。

端口 25 不是赢家，因为 EC2 默认启用了激进的速率限制，以防止明显的垃圾邮件问题，否则会发生。您可以通过提交支持请求来要求禁用此功能，但最简单的解决方案是仅使用端口 587。

那么，您的客户端没有设置发件人地址，因为没有指定from 地址。
