You’re right, I should give you definitions for namespaces.

Here it is:

namespace {
  inbox = no
  list = children
  location = maildir:/var/mail/%d/__public__/maildir/:LAYOUT=fs:INDEX=~/indexes/public/
  prefix = "#Public/"
  separator = /
  subscriptions = no
  type = public
}

so, #Public (/var/mail/domainname/__public__) is the “root” of my namespace, “sys” is a folder inside #Public.

Anyway, I’ve solved putting correct permissions in ACLs. One thing: I did not find anywhere informations about the necessity to put an ACL even on “root” of namespace. I’ve added a proper dovecot-acl file in /var/mail/domainname/__public__ and wverything started to work.

Anyway, thanks again for your effort in deciphering my previous post :) and thanks for the great program dovecot is!
