Insight for: mac docker启动项目无法安装插件

A user reports a critical failure to install plugins when running `any-auto-register` via Docker on macOS, evidenced by a `500 Internal Server Error` during the `/api/integrations/services/cliproxyapi/install` call. This indicates a significant deployment and functionality issue specific to the Dockerized environment on Mac, potentially related to file permissions, network access, or internal service communication within the container. Concurrently, the user requests custom domain support for Duckmail, highlighting a need for greater flexibility in email service integration beyond the default `duckmail.sbs` domain. Both issues point to limitations in the project's deployment robustness and customization options, impacting its utility for advanced users.
