Can anybody point me at documentation on how calendar invites over email work? It's something I've wondered about for ages but never understood and finding info on the fine details really hard.
I know that CalDAV lets you sync calendars around.
I know that you can send a calendar invitation via email.
I DON'T know how this happens. Presumably the CalDAV server sends it via SMTP From: the organiser?
I know that you can RSVP to an invitation via email
I DON'T know how this response gets back onto the organiser's calendar. Presumably the CalDAV server is hooked into mail somehow and looking for iCal attachments?
This interplay between creating/updating events and them being sent around via email and then magically updating the calendar is the bit I'm confused about.
