我似乎无法让 Prayer Webmail 运行 https 端口。我在 Ubuntu 16.04.2 上运行 Exim4+Dovecot。
它在不安全的 http 端口上运行良好——除了它是不安全的（我将端口 8888 用于 http，将端口 8843 用于 https）。
该端口在防火墙中打开。如果我在 8843 上设置一个套接字，我可以连接到它，测试防火墙。
我已经尝试了几个不同的端口，所以不是这样。
在运行时，我没有得到明显的错误。我遵循了我能找到的所有文档，它在配置文件中对我来说看起来是正确的，但它只会打开 http 端口。如果我禁用了pray.cf 中的http 端口，它将不会像它所说的那样运行，或者没有配置为打开的端口。
它能够很好地加载 .key 和 .crt 文件（如果我更改某些内容，它会因错误而关闭，所以它不能）。
有人知道如何让它在 https 上运行吗？

好的。所以看起来祈祷实际上是在指定的 https 端口上监听......有趣的是，在测试时我正在使用 nmap 扫描打开状态，并且扫描显示从内部或外部关闭，但我的浏览器连接并且我能够在指定端口上登录到祈祷 ove https，但它仍然在扫描时显示已关闭。
这怎么可能？
