向一个特定域发送电子邮件，我收到以下错误：

   ----- The following addresses had permanent fatal errors -----
<>
    (reason: 403 4.7.0 TLS handshake failed.)

   ----- Transcript of session follows -----
<>... Deferred

想知道这是否是我的邮件服务器或收件人的问题...

所以这发生在两个域上......他们都使用 Outlook.com 作为邮件提供商：

openssl s_client -starttls smtp -connect x-com.mail.eo.outlook.com:25

我正在尝试将文件夹的所有子目录移动到同一服务器上的另一个共享。如果我执行 mv *，我将用完空间，因为在所有文件夹都转移之前不会删除文件夹。所以我想创建一个循环遍历每个脚本的简短脚本。有人有我可以看的例子吗？我四处搜寻，但找不到我要找的确切内容。

我们有 2 台服务器，每台位于不同的地理位置，我们正在考虑使用 rsync 脚本来保持某些文件夹同步。我们的设置禁用 root 登录和密码登录，并依赖于密钥文件。

我们在端口 22X 上运行 SSH（只是为了尽量减少登录尝试，而不是通过默默无闻的安全方式）。

如果我们设置端口转发使端口 XYZ 转发到 22X，并禁用密码登录，我们应该采取哪些其他措施来防止由于开放端口而发生的任何恶意活动？

我的想法是，只要我们保证密钥安全，就不会有问题。我错过了什么吗？

我今天在我的邮件服务器上发现了一些奇怪的东西。我的收件箱中有一条消息说：

Received: from myserver.com (localhost)
    by myserver.com (8.14.3/8.14.3/Debian-9.2ubuntu1) id r3GJ4H5S005124;
    Tue, 16 Apr 2013 19:05:02 GMT
Date: Tue, 16 Apr 2013 19:05:02 GMT
From: Mail Delivery Subsystem <[email protected]>

这是一条似乎从我的服务器发送的消息的反弹。日志显示我收到了来自该地址的垃圾邮件，但我粘贴在下面的日志的最后一行引起了我的注意。我如何向这个电子邮件地址发送“TO”消息？我可以保证我从未回应过，等等。

这是在 ubuntu 上运行 sendmail。
