All those editors did
when they decided it wasn't publishable. it isn't that it has not been peer-reviewed but that it has failed peer review.
That's a painful moment in one's life - I've had a several papers knocked back but if you can rework the better parts and discard the lesser, you end up with a good publishable paper in the end.
if nothing survives that process, you're either a genius, or you're wrong...
