我已经设置好邮件服务器，通过 HTTP API 将邮件转发到 Discourse，这已经可以正常工作了。现在我想启用 `reply_by_email` 功能，以便用户可以直接回复邮件。

因此，我尝试启用 `reply_by_email`，但 Discourse 拒绝了我的请求：

```plaintext
discourse(prod)> SiteSetting.reply_by_email_address
=> "reply+%{reply_key}@<our-valid-domain>.de"
discourse(prod)> SiteSetting.email_in
=> true
discourse(prod)> SiteSetting.reply_by_email_enabled = true
lib/site_settings/type_supervisor.rb:271:in `validate_value': reply_by_email_enabled: 在启用通过电子邮件回复之前，您必须启用手动、POP3 轮询或自定义邮件轮询器。 (Discourse::InvalidParameters)
    from lib/site_settings/type_supervisor.rb:177:in `to_db_value'
    from lib/site_setting_extension.rb:623:in `add_override!'
    from lib/site_setting_extension.rb:990:in `block in setup_methods'
    from (discourse):15:in `<main>'

```

有人能帮忙吗？

谢谢！  
Hans
