I've been learning this, and was just about to post a retraction when I 
saw your message.  :)  I'm flat out wrong, and thrilled to see it.  :)  
Venema is quick to caution that the Milter interface can be a serious 
drag on performance though, which is why it wasn't implemented sooner.  
I hope to experiment with it and see how reasonable it is to use this 
method in a large volume scenario.
