I was facing same problem, To work quota_clone_dict, you need to define quota_rule Even quota_rule with unlimited quota will not work here UN-Comment below line in your dovecot.conf. #quota_rule = *:storage=5G
if you type zmprov view quota in your favorite search engine the first hit you find is: https://wiki.zimbra.com/wiki/Getting_All_Users_Quota_Data which to me really does what you need.
