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 - 除了它不安全（我对 http 使用端口 8888，对 https 使用端口 8843）。
防火墙中的端口已打开。如果我在 8843 上设置套接字，我就可以连接到它，测试防火墙。
我尝试过几个不同的端口，所以不是那样。
运行时，我没有发现任何明显错误。我遵循了所有我能找到的文档，配置文件看起来是正确的，但它只会打开 http 端口。如果我在 pray.cf 中禁用 http 端口，它就不会运行，因为它说没有配置要打开的端口。
它可以很好地加载 .key 和 .crt 文件（如果我更改某些内容，它就会因错误而关闭，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 pray 实际上正在监听指定的 https 端口……有趣的是，在测试时，我使用 nmap 扫描开放状态，扫描结果显示无论是从内部还是外部都已关闭，但我的浏览器已连接，我能够通过 https 在指定端口上登录 pray，但扫描结果仍显示已关闭。
这怎么可能？
