我不知道SMTP服务出了什么问题

安装

我使用 mailgun.com 的服务发送邮件，但按照教程设置的 SMTP 不起作用。我甚至无法完成管理员注册

您需要检查安全选项，因为它不是很精确，您需要将其关闭（同时不影响您的安全性）。

您为什么要为 Mailgun 使用沙盒账户？您应该使用与您的社区域名对应的 postmaster 账户。

您在添加和授权与您的社区对应的域名时遇到问题了吗？

您的社区配置为从哪个电子邮件地址发送电子邮件？

您需要禁用沙盒模式，我认为该模式只能发送到单个地址。没有理由不正确配置 Mailgun。

请参阅疑难解答新 Discourse 安装中的电子邮件。

我使用 Mailu 构建了一个 SMTP 服务，可以收发邮件

哦，我通过打开 SSL 解决了这个问题

这是否意味着我应该为 Discourse 打开 SSL 设置？

所以你放弃了 mailgun，决定使用一个没人听说过的东西？

它说它不允许你从 norepy@bbs.doublekm.xzy 发送。将通知电子邮件更改为 Makima@bbs.doublekm.xyz，看看是否有效。
