Every service running under master accepts -o, as far as I can tell from
the code. (Additionally verified by my tests; for settings without spaces
it works well.)

It's just a setting that you'd normally set in conf.d/90-quota.conf (or
similar) like this:

plugin {
  quota_status_success = DUNNO
}

It tells quota-status what action to return to Postfix when the message
will fit into quota, just like quota_status_overquota (and
quota_status_toolarge since 2.2.5) do for messages that will not fit.
