在我的WebHostpipe理器中的VPS我有一个称为邮件队列pipe理器的区域。 我经常会在那里build立一些似乎含有病毒和其他问题的信息。
这些消息到底是什么？ 他们是否试图将邮件传递到我的域名？ 或者他们的消息是以某种方式试图通过从我的域名发送？
我很担心，我的服务器不安全，垃圾邮件发送者正在使用它。 这个消息是否证实或否认？
注意：我将[email protected]转发到[email protected]，我从Gmail发送邮件，但是使用我的MYDOMAIN.com SMTP服务器。

您需要configuration您的vps的防火墙closures端口25到外部stream量。
如果你想从你的networking服务器发送邮件，你仍然可以做到这一点与端口25封闭的外部世界，防止99％的问题。
如果您需要使用SMTP服务器进行外部通信，请使用托pipe公司提供的服务器。
否则，你将花费绝大部分时间来保持你的SMTP服务器补丁和closures恶意stream量。

垃圾邮件发送者通过您的服务器将电子邮件转发到外部世界。 您的电子邮件服务器被configuration为开放中继，因此正在发生。

服务器configuration不正确，因此是不安全的。 但是，有一个简单的方法来解决这个问题：
