Some mailing lists use such a scheme.  The qmail list for one.  The list 
was spammed heavily and so the owner invoked the same type of confirmation 
system.  When you post to the list, a program called qsecretary sends you 
an automatic reply to which you must then reply back and your reply MUST be 
from the same envelope sender as is registered with the list.  It's highly 
effective but certainly not for everyday email.  God help us!  ;)
