Dovecot first finds the mountpoint and then gets its filesystem. If it's
nfs, it uses rquota, otherwise local quota. You could enable
mail_debug=yes and see what mountpoints Dovecot finds and then see if
their type is nfs or something else. Also this would make checking the
type (correctly) even easier:
