So, the "connect the dots" is to:

- Announce the fact example.com is hosted at calendarserverfoobar.com (with 
some URL) in DNS

- Secure that announcement in DNS with DNSSEC

- Verify the SSL (for example) cert for the connection to 
calendarserverfoobar.com matches

- Do application layer authentication etc over the then encrypted connection

Sounds ok?
