I have no experience using disk quota's but I think something like this 
should work:

plugin {
   quota = fs:Disk quota
   quota_rule = INBOX:storage=<whatever max you like>
   quota_warning = storage=95%% /usr/local/bin/quota-warning.sh 95
}

AFAIK, the backend is only used as a way to determine the used space, 
not as a way to define the limits. So you need to specify the maximum 
quota; the filesystem quota is not recognized. E.g. when specifying 
maildir as backend Dovecot will check the maildir quota in stead of 
using used diskspace as reported by the OS.
