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 client. 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...
