We've configured Darwin Calendar Server on a Linux machine. Everythin works quite okay except one thing: Invitations Am I right thinking, that Lightning doesn't support sending/receiving Event-Invitations using only the server? Is the only way of sending receiving event invitations in lightning via e-mail? In iCal I can add participants and click on "send", but my colleagues don't seem to receive anything. So I have to send them invitations via an e-mail with an ics file attached, which renders the participants feature of iCal useless. We tried to access the "inbox" collection from within lightning but without success. Any workarounds to get the iTip/iMip mechanisms to work with Darwin Calendar Server and Lightning?
