It is easy to do with any number of mailers and there is nothing illicit
about it, and it can be quite useful when replies really should go only
to the individual rather than the list (surveys and such).

This is controlled by your list header with the reply keyword.  It
sounds like you want something like List,Ignore . Personally I really
like Both,Respect as it is very flexible, and I am in favor of that.
