caldav and invitation

[Zorg]

Hello

I try to configure my cyrus to use caldav correctly

Caldav working nice but when I try to invite someone nothing happen

Let me explain

I have to user "toto at test.domain.com" and "titi at test.domain.com"

if toto at test.domain.com create a event and invite titi at test.domain.com

i ve got this in the log

imip_send_sendmail(titi at test.domain.com): Sendmail process terminated 
normally, exit status 0

But if i look in the calendar of titi or in the mailbox I see nothing (I 
ve have been testing with thunderbird and evolution)

There is nothing explaining well how it is supposed to work in the  
cyrus documentation so maybe i'm missing something

does someone could explain what to expect when i invite someone in a event

Hope I'm clear


Thanks
