I came to this thread purely to see if I was the only enlightened one.

Stalwart is perfect for small self-hosters: a single binary, a single-directory resilient datastore (by default), a UI for every setting, and defaults that guide you to a DNS config which maximizes your sender score. Plus support for all of the "power user" features such as ManageSieve and shared CalDav folders.

Honestly, I love hosting my email now. And the last remaining battery which could possibly be included is now WIP: webmail!

Unix philosophy need not apply when there is exactly one use case for integrating these tools. (Or at least, one case which covers 99% of users. The remainder can keep their managerie of arcane config formats and susceptibility to unsafe language CVEs.)
