There is unfortunately no "default ACL" feature currently. Although you could somewhat easily add an ugly hack to the code for that. And I guess it wouldn't be difficult to implement it, maybe by reading it from $mail_root/dovecot-acl-default file or something..

So without code changes you could:

 - create all of the necessary folders
 - set such ACLs that user can't create any more folders
 - disallow expunging in all folders
