在MXRecord上运行诊断时出现的hMailServer错误

Question

我已经下载并安装了hmailserver。我想在我的本地机器上运行它，并希望使用本地web应用程序发送电子邮件，该应用程序也运行在我的本地机器上。我的web应用程序无法发送电子邮件(got错误- couldn't connect to mydomain:25)，因此我想首先运行hmailserver的诊断工具来测试事物。

但是当我在上面运行诊断时，我看到了错误：

Test: Collect server details hMailServer version: hMailServer 5.6.7-B2425 Database type: MSSQL Compact

Test: Test IPv6 IPv6 support is available in operating system.

Test: Test outbound port SMTP relayer not in use. Attempting mail.hmailserver.com:25... Trying to connect to host mail.hmailserver.com... Trying to connect to TCP/IP address 5.189.183.138 on port 25. Received: 220 mail.hmailserver.com ESMTP. Connected successfully.

Test: Test backup directory ERROR: Backup directory has not been specified.

Test: Test MX records Trying to resolve MX records for mydomain.com... ERROR: MX records for domain mydomain.com could not be resolved

Test: Test local connect Connecting to TCP/IP address in MX records for local domain domain mydomain.com... ERROR: MX records for local domain mydomain.com could not be resolved

Test: Test message file locations Relative message paths are stored in the database for all messages.

Test: Test IP range configuration No problems were found in the IP range configuration.

老实说，我不知道MX Record是什么，也不知道如何设置它。到目前为止，我所做的是：

1. 安装了hmailserver (显然！)
2. 添加了一个域(mydomain.com)
3. 在mydomain.com (signup@mydomain.com)中添加了一个帐户
4. 在设置->协议->SMTP中，我在电子邮件->Localhostname部分的传递中添加了本地主机。
5. 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
6. 当我运行netstat -a时，我看到hmailserver在监听port 25 (我使用net stop hmailserver和net start hmailserver进行了测试) Proto Local Address Foreign Address State TCP 0.0.0.0:25 DESKTOP-6PLQOLJ:0 LISTENING[/list]

我犯了什么错误吗？

Answer 1

如果您的Windows操作系统DNS-Resolver服务指向一个DNS-Server，该DNS-Server不知道或不能将查询转发给负责指定域及其MX-记录的DNS-Server，则会显示此错误消息。

简而言之:如果没有正确配置DNS-域，hMailServer (或任何其他SMTP-Server)就无法工作。
