Is there a CalDav client with email alert support on Ubuntu server?

http://askubuntu.com – Assume I had an Ubuntu Server with a CalDav server (in my case this is ownCloud 3), but the server didn't allow sending of calendar events by email to me. I'm looking to install a CalDav client, on the same server (must be command line driven), which I can subscribe to the CalDav server (on the same server), which will send out email alerts to me on events I put in there. Any client as such available? (HowTos)
