ACL to deny move mailbox/folder

Hi,

I got a shared folder where I want users to be able to create
subfolders, but where I want to restrict the users so they do not move
or delete the shared folder. The folder is a top level shared folder.

I read through the cyradm documentation, but it wasn't very clear on how
to do this. Is it possible?

Should I consider other ways to do this - for example change the file
permissions of the mailbox directory directly?

All tips are welcome.

Kind regards,
Tarjei
