Node.js nodemailer错误-错误版本号/无效问候语

Question

在我的node.js服务器上设置nodemailer有一个很大的问题。我在网上发现的每一件事都试过了，但都没有用。唯一容易设置的就是gmail服务。但不幸的是我不能用那个。

当secure设置为true时，我得到一个错误版本代码的原因。

[Error: 22468:error:1408F10B:SSL routines:ssl3_get_record:wrong version number:c:\ws\deps\openssl\openssl\ssl\record\ssl3_record.c:332:
] {
  library: 'SSL routines',
  function: 'ssl3_get_record',
  reason: 'wrong version number',
  code: 'ESOCKET',
  command: 'CONN'
}

但是，当我试图将secure设置为false时，就会得到一个无效的问候语错误。

  command: 'CONN'
}

我的代码如下：

const transporter = nodemailer.createTransport({
  host: process.env.MAIL_HOST, // mx.example.com
  port: process.env.MAIL_PORT, // 143
  secure: true,
  auth: {
    user: process.env.MAIL_ADDRESS,
    pass: process.env.MAIL_PWD
  }
})

我已经检查了上千次了，他们绝对不是问题所在。

希望有人能帮我。提前谢谢。

Answer 1

提到这里提到的这个问题：https://github.com/andris9/Nodemailer/issues/165

查看这是否有帮助，添加tls.ciphers选项以使用SSLv3

const transport = nodemailer.createTransport({
    host: process.env.MAIL_HOST, // mx.example.com
    port: process.env.MAIL_PORT, // 143
    secureConnection: false, // TLS requires secureConnection to be false
    auth: {
        user: process.env.MAIL_ADDRESS,
        pass: process.env.MAIL_PWD
    },
    tls: {
        ciphers:'SSLv3'
    }
});

对于Outlook365，这应该是可行的：

service: "Outlook365",
auth: {
   user: '[YOUR_O365_EMAIL]',
   pass: '[YOUR_O365_PASSWORD]'
}, 

请参阅此处：https://stackoverflow.com/a/37725123/9360885

如果您使用的是HotMail，那么删除host和port，然后添加service: "hotmail"。

Answer 2

使用

secure: false, // true for 465, false for other ports

nodemailer文档中的示例：

let transporter = nodemailer.createTransport({
    host: 'smtp.ethereal.email',
    port: 587,
    secure: false, // true for 465, false for other ports
    auth: {
        user: account.user, // generated ethereal user
        pass: account.pass  // generated ethereal password
    }
});

Answer 3

我在Gmail中使用了端口465，这起作用了。得到了“错误的版本号”错误与587。下面的示例用于云函数中的GCP服务帐户。

  const transporter = nodemailer.createTransport({
    host: "smtp.gmail.com",
    port: 465,
    secure: true,
    auth: {
      type: "OAuth2",
      user: process.env.GMAIL_ADDRESS,
      serviceClient: process.env.CLIENT_ID,
      privateKey: process.env.PRIVATE_KEY.replace(/\\n/g, "\n"),
    },
  });
