As part of my journey to start self-hosting email for my domain, I have found plenty of tutorials and solutions to "easily" setup SMTP,IMAP/POP and webmail, all of it securely.
Now I'm looking at the solution available to add CalDav and CardDav on top of all of this. The obvious choice seems to be SoGO. Documentation seems decent, there are a few things on Archs wiki. I've been unable to find a how-to. SoGO looks like a very complete solution. I've used it, and I liked it. Now I'm thinking it might be overkill for my 10ish users (and I'll probably be the only one using it anyway). I've been looking at other solutions - but didn't find anything as complete. What are my options for caldav/cardav that would integrate with postfix/dovecot?
