Frontend cannot create sub-level mailbox

Some upgrades:
I tried to reinstall everything splitting the frontend and the Mupdate
server in two different PC.
I Installed the 2.3.16 version of Cyrus Imap, because i saw is
functioning for someone.
I replicated the same confirguration as mentioned in my precedent posts
and everything is working, so i can create sublevel mailbox from my Imap
So, my problem may be caused:
- or by a configuration mistake setting a frontend as a mupdate server
- or by a problem in the current version of Cyrus Imap (but i believe it
is unlikely)
Tomorrow I'll install the current version in the working environment, so
I'll have an answer.
Suggestions are welcome...
