You have a valid point regarding nginx for static content and its simplicity.

The rest of what you wrote is either wrong, oversimplified, or inaccurate.

Thing I've never understood with nginx is why would I want my web server to also be my mail server?

I think most nginx deployments only do web, but the article on mail functionality does outline some of the reasons: https://docs.nginx.com/nginx/admin-guide/mail-proxy/mail-pro...

Besides those listed I think a plus would be to only have one server listening on priviliged ports (<1024), using the same/similar TLS configuration for both web and mail, etc. Basically having one service be the arbiter of your incoming traffic and its encryption.

Some people also throw dns via DoH/DoT in: https://www.f5.com/company/blog/nginx/using-nginx-as-dot-doh...

I suppose the technology inside nginx provides similar benefits as mail proxy as it would for a web proxy.
