Using Postfix debug I understand where the problem come from.

My kolab systems are multi domain, but not all domains are equal in postfix.
The first domain, the one you define during first startup, the one is in main.cf in mydomain, 
does not do client access check when you send a mail to special users like postmaster.
All other domains and all other user of first domain instead do.

The first check done by postfix is the IP address of clients.

So only first domain can receive mail for special users like postamster also from blaklist IP.
