我有以下作为我的nodemailer脚本：
'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' }
我有我的configuration设置后缀使用端口465和587，仍然得到相同的响应。 也许这是调用本地主机的问题，即使我的后缀服务器设置与主机是我的网站域？ 我也有我的后缀设置与SSL。 任何想法都欢迎。 提前致谢。
更新：我90％确定这是我提供给nodemailer的凭据的问题，但我无法find断开连接的位置。 后缀服务器在自己发送消息，但不通过脚本工作正常。 我已经尝试了不同的端口和不同的configuration设置，但我无法弄清楚什么是错误的，错误是不是很有帮助。
这是我的后缀main.cf文件

在nodemailer脚本中，我传递了我的服务器上正在接收邮件的帐户的用户名和密码。 我可以通过命令行发送和接收邮件，但是我还没有成功通过这个脚本发送。 非常感谢您的帮助。 我正在运行Ubuntu 16.04。 我已经尝试通过ufw允许端口号。
