I'm aware of that. As far as I'm concerned it's a bug.

Callout is a somewhat borderline tactic in any event (certain large
mail services, superficially an attractive target for callout
verification due to frequent forgeries, _will_ block you if they catch
you doing it). We use it only as a way of informing people that they
are blocking us (turning it on for those specific domains means that
they get to see their own rejection message in our response).
