I'm setting up Stalwart right now, migrating from my current Maddy+Postfix+Dovecot+Rspamd setup. Not exactly my experience.
The documentation is not great - I'd say it's just about barely enough to get an overall idea, but there's no one proper single definitive overview of what options exist, what are their possible values, what are the defaults, and how they relate to each other. Maddy docs, despite looking a bit sloppy, were a lot easier to get through. IMHO Stalwart makes it unnecessarily difficult to write a non-minimal static configuration file, hooking everything up correctly.
To be fair, maybe there is a page like that but I haven't found it, despite trying.
I know the Web UI allows to do the configuration by clicking through the forms, but this approach conflicts with declarative deployment practices. In my case it's giving me nondescript 500 errors in the UI with "Failed to write local configuration" in the logs because the .toml file is read-only.
