我的 nodemailer 脚本如下：
'use strict';
const nodemailer = require('nodemailer');
// create reusable transporter object using the default SMTP transport
let transporter = nodemailer.createTransport({
host: 'localhost.com',
port: 465,
secure: true,
auth: {
user: 'user',
pass: 'pass',
}
});
module.exports = (msg) => {
let { from, to, subject, html } = msg;
// setup email data with unicode symbols
let mailOptions = {
from,
to,
subject, // plain text body
html,
};
transporter.sendMail(mailOptions, (error, info) => {
if (error) {
return console.log(error);
}
console.log('Message %s sent: %s', info.messageId, info.response);
});
}
当我尝试运行该函数时收到以下错误：
{ Error: 139970611431232:error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol:../deps/openssl/openssl/ssl/s23_clnt.c:794:
code: 'ECONNECTION', command: 'CONN' }
我确实已将 postfix 的配置设置为使用端口 465 和 587，但仍然得到了相同的响应。也许是因为在 localhost 上调用存在问题，尽管我的 postfix 服务器已将主机设置为我的网站的域？我的 postfix 也已使用 ssl 设置。欢迎提出任何想法。提前致谢。
更新：我 90% 确定这是我提供给 nodemailer 的凭据的问题，但我找不到断开连接的位置。postfix 服务器可以自行发送消息，但不能通过脚本发送。我尝试了不同的端口和不同的配置设置，但我无法找出问题所在，错误也没有什么帮助。

在 nodemailer 脚本中，我传入了接收邮件的服务器上的帐户的用户名和密码。我可以通过命令行正常发送和接收邮件，但通过此脚本发送邮件却没有成功。非常感谢您的帮助。我正在运行 Ubuntu 16.04。我尝试通过 ufw 允许端口号。

更新：仍然有这个问题...无法弄清楚我的 postfix 设置出了什么问题，导致允许通过终端发送电子邮件但不允许通过 nodemailer 发送电子邮件。
答案1
设置安全标志为 false，安全标志设置“SSL”。这并不意味着您的电子邮件不安全。它现在将使用 STARTTLS，这更加安全！
let transporter = nodemailer.createTransport({
host: 'localhost.com',
port: 465,
-> secure: false,
auth: {
user: 'user',
pass: 'pass',
}
});
答案2
const transporter = nodemailer.createTransport({
port: 25,
host: 'localhost',
tls: {
rejectUnauthorized: false
},
});
var message = {
from: '[email protected]',
to: '[email protected]',
subject: 'Confirm Email',
text: 'Please confirm your email',
html: '<p>Please confirm your email</p>'
};
transporter.sendMail(message, (error, info) => {
if (error) {
return console.log(error);
}
console.log('Message sent: %s', info.messageId);
});
我目前正在通过 express.js 上的 restful api 触发此操作
这应该可以工作，我用它在 digitalocean 上设置我的 postfix：https://www.digitalocean.com/community/tutorials/how-to-install-and-configure-postfix-as-a-send-only-smtp-server-on-ubuntu-16-04
