如何使用 nodemailer 和 dreamhost 发送电子邮件（在 Node.js 服务器上）

Question

我找不到任何特定于使用 nodemailer 从 dreamhost 发送电子邮件的有用帖子。我确实找到了一个 dreamhost article for sending emails via PHP，所以也许这可以帮助我们指明正确的方向...

无论哪种方式，这是我的 mailer.ts 文件：

import { createTransport, getTestMessageUrl } from "nodemailer";

import { frontendURL } from "./urls";

var transport = createTransport({
  host: "smtp.dreamhost.com",
  port: 465,
  auth: {
    user: encodeURIComponent(process.env.PROD_MAIL_USER),
    pass: encodeURIComponent(process.env.PROD_MAIL_PASS),
  },
  secure: true,
});

function generateHTML(resetToken: string) {
    return `
      <div>
        <h2>Hello from HaBits </h2>
        <p>
          Your <b>Password Reset Token</b> is here!
        </p>
        <h3>
          <a href="${frontendURL}/reset?token=${resetToken}" style="color: #75B748">Reset your password.</a>
        </h3>
        <p>HaBits ✅</p>
      </div>
    `;
}

export interface MailResponse {
  accepted?: string[] | null;
  rejected?: null[] | null;
  envelopeTime: number;
  messageTime: number;
  messageSize: number;
  response: string;
  envelope: Envelope;
  messageId: string;
}

export interface Envelope {
  from: string;
  to?: string[] | null;
}

export async function sendPasswordResetEmail(
  resetToken: string,
  to: string
): Promise<void> {
  // email the user a token
  const info = await transport.sendMail({
    to,
    from: process.env.PROD_MAIL_USER,
    subject: "✅ HaBits – password reset token",
    html: generateHTML(resetToken),
  });
}

生产中的错误响应：

    "errors": [
        {
            "message": "Invalid login: 535 5.7.8 Error: authentication failed: ",

                }
            },
            "name": "GraphQLError"
        }
    ]
}

Dreamhost“支持”刚刚向我发送了关于 PHP 的文章，该文章建议使用 host: "ssl://smtp.dreamhost.com"，但只是 returns 一个不太有用的“找不到地址”错误：

Error: getaddrinfo ENOTFOUND ssl://smtp.dreamhost.com

所以我非常有信心 nodemailer 配置是正确的 – 即。主机、端口、用户和密码

这是我自己的愚蠢错误‍♂️

这是用于在生产环境中发送电子邮件的 nodemailer 配置（假设您有一封由 dreamhost 托管的电子邮件）：

import { createTransport, getTestMessageUrl } from "nodemailer";

var transport = createTransport({
  host: "smtp.dreamhost.com",
  port: 465,
  auth: {
    user: process.env.PROD_MAIL_USER, // your email address
    pass: process.env.PROD_MAIL_PASS, // your webmail password
  },
  secure: true,
  logger: true,
  debug: true,
});

// ...

await transport.sendMail({ ... })

我的问题是 encodeURIComponent() 包裹着我的电子邮件和密码 – 所以电子邮件 hello@example.com 被传递为 hello%40example.com。

上面的 logger 和 debugger 属性是可选的，但它们帮助我确定了服务器日志中的问题。
