Thanks for response.
But it is out of question that I use a commercial certificate because I have an internal PKI.
In my ZCS (trial 60 days licence), I use the standard certificates and key provided by Zimbra : /opt/zimbra/ssl/zimbra/server.
Later I will use a certificate signed by my proper CA.
None use a "private" PKI ? Or any selfsigned certificate ? Plz...
