Interesting. Always great to see JMAP support, even though I don't 
actually have a client that supports it yet. Theoretically very cool.

I find most postfix settings were not needed, until they were.

Not sure if the AIO does more, but Nextcloud itself only provides DAV 
services, it doesn't provide mail hosting. There's a mail client app, 
but it expects a separately hosted IMAP server somewhere. It's alsy 
*very* barebones.

NC's AIO supports running containers (I think, I don't use AIO), so 
maybe they've packaged something since.

FWIW, I'm using Nextcloud for file sync, because it's the only option 
that hasn't regularly broken during upgrades (seafile), or required 
additional brain-power to remember how to access files on it 
(syncthing). But I'm not using it's CardDav/CalDav features at all.

I may look at setting up stalwart to act as a backup for my 
mail/card/contacts, though. It's pretty interesting.
