I’ve been using radicale for contacts and calendar for quite a few years now. Plays nice with iOS Mail and Contacts as well as Gnome Evolution and has overall been a great experience.

I'm a happy radicale user too but I haven't been able to get it to work w macOS mail and contacts. I use EMClient with it which works great.

Thanks, that's very helpful. I'll have to see if importing a Letsencrypt certificate works?
