Looking for a simple card/cal/WebDAV server that runs in docker.
Have tried Davis, Radicale and Baikal but have either struggled to get them working or found them a bitch to maintain.
Doesn’t have to be a DAV type solution. Syncing/backing up contacts and calendars from an android phone is essential.
I think you got a downvote for promoting mailcow, users can be fickle
Or maybe just because there is nothing simple in hosting a mail server for having card and caldav.
It is indeed rather complex.
