This could be used in identifying it as a response. (I guess that 
"structure" is because of your sanitation and you got a "good" MID there 
back?)

In general I find that quite a few DSNs don't list important or any parts 
of the mail or mail header, especially not headers that are uncommon. So, 
these will all be blocked. But it doesn't happen that often that mail to 
your frequent mail contact bounces, so you will rarely notice it. The 
read-receipt is a good example where you notice it quicker ;-)
