I would like to see the bounce processing enhanced to handle this
situation.  If I remember correctly I think I saw where version 3 will be
able to have it set to handle bounces on a global basis instead of per
list?  If that is the case, it will be taken care of in version 3.  I am
not sure what the timetable is for version 3, but it might be worth just
waiting.  But, I would love to see it in version 2 if it is not that big of
a change.
