So, you agree, MTA's do not implement this functionality.  It's obviously
possible to make it happen through shell scripting, database tricks, etc.,
but the point was that if this was commonly desired, then MTA's would be
supporting it directly.  It isn't commonly desired, most people just block
"forever."

It never ceases to amaze me how technical people so often easily miss the
point.  :-)
