我已经下载并安装了hmailserver. 我想在我的本地机器上运行它，并想使用也在我的本地机器上运行的本地 Web 应用程序发送电子邮件。我的 Web 应用程序无法发送电子邮件（出现错误 - couldn't connect to mydomain:25），因此我想先运行hmailserver的诊断工具来测试。
但是当我对其进行诊断时，我看到了错误：

老实说，我不知道MX Record它是什么以及如何设置它。到目前为止我所做的事情是：
- 安装了 hmailserver（显然！）
- 添加了一个域 (mydomain.com)
- 在 mydomain.com (signup@mydomain.com) 中添加了一个帐户
- 在设置-> 协议-> SMTP 中，我在 Delivery of email -> Localhostname 部分添加了 localhost
- 在
c:\Windows\System32\Drivers\etc\hosts文件中，我添加了条目127.0.0.1 mydomain.com #for play application - 当我运行时
netstat -a，我看到它hmailserver正在监听port 25（我使用net stop hmailserverand对其进行了测试net start hmailserver）Proto Local Address Foreign Address StateTCP 0.0.0.0:25 DESKTOP-6PLQOLJ:0 LISTENING[/list]
我犯错了吗？
