Nodemail x Node.js：虽然测试成功但验证失败

Question

我在使用 nodemailer Firebase 函数时遇到问题，该函数应该通过 SMTP 传输器发送电子邮件。

这很奇怪，因为我正在使用以下方法成功测试我的连接：

// check server readiness
const serverReady = await new Promise<boolean>(resolve => {
  transporter.verify( (err: any, succ: any) => {
    if (err) {
      console.log(err);
      resolve(false);
    } else {
      console.log('Server is ready to take our messages');
      resolve(true);
    }
  });
})

打印Server is ready to take our messages。

然后在设置我的信封并使用.sendMail 方法发送后，我收到此错误：

Unhandled error { Error: Mail command failed: 530 5.5.1 Authentication Required.
    at SMTPConnection._formatError (/srv/node_modules/nodemailer/lib/smtp-connection/index.js:777:19)
    at SMTPConnection._actionMAIL (/srv/node_modules/nodemailer/lib/smtp-connection/index.js:1546:34)

  code: 'EENVELOPE',
  response: '530 5.5.1 Authentication Required.',
  responseCode: 530,
  command: 'MAIL FROM' }

错误很明显：Failed Auth，但很奇怪，因为测试工作较早！

连接参数为：

// options to connect to server
const smtpOptions = {
  host: 'smtp.zoho.eu',
  port: 465,
  secure: true,
  auth: {
    user: functions.config().nodemailer.user,
    pass: functions.config().nodemailer.pass
  }
};

// transporter for sending the email
const transporter = nodeMail.createTransport( smtpOptions );

提前谢谢大家

transporter.verify 仅测试连接和身份验证，看起来您无权使用特定的MAIL FROM 地址。
