I did mention Bernstein's ezmlm, where I picked this up originally. It's  
likely that he was the first one to come up with this, circa 1997. Certain  
aspects of Qmail which, I'm pretty sure had no equivalents in other popular  
MTAs of that time, made this approach a natural fit; so that's where this  
likely came from, but I could not be sure.
