Cloudron is kind of a freemium product. They offer a few apps (two ?) for free to use. For more apps you need to pay. Their back-end does have a view-source-but-no-edit “open source” license last time I checked. Bu if you want to keep things easy, go for it.

I’ve tried Snikket a few years ago. Nice project. 👍

If your real SMTP server is doing fine, nullmailer is possibly the simplest of all smtp relay packages available.

Run Caddy as reverse proxy for example : https://caddyserver.com/docs/caddyfile/directives/reverse_proxy#examples Syntax is pretty simple and Caddy can automatically do the SSL certificate handling for you as well. No need to install Certbot.
