[CalendarServer-users] iMIP replies and Lighning interoperability

I'm trying to configure DCS on openSUSE 10.3 for a mixed Linux/MacOS  
environment using XML file authentication.

There is few information available about DCS / Lightning  
interoperability. It seems Lightning does not processing scheduling  
requests in the scheduling inbox on the server, and does not send  
invitations through DCS either. Was someone sucessful in getting that  
working, or is that not yet supported in Lighning?

I got the iMIP scheduling in DCS only partially working: Known users  
are asked internally (for iCal, see above), and external users get an  
invitation email. Problems arise when DCS tries interpreting and  
injecting email replies. I use the builtin mail templates and have  
enabled plus-addressing on the mail server. I've added an entry to the  
XML file for the  com.apple.calendarserver and the respective GUID to  
the »principals with "DAV:all" access«.

Depending on the client (both most recent version) I use to create the  
reply email I get the following errors:

After adding an cuaddr to the calender user entry, I also got errors  
when trying to schedule an event.

And for interpreting Lightning/Thunderbird replies the error changes to:
