Errors-To: is completely meaningless; please do not use it. I suspect that
you really intend to have something sit at the address that is used as the
envelope sender, generally owner-listname.
In any case, a tool like this is greatly needed and is somewhat difficult
to do. I designed one on paper but haven't had the time to actually write
it. Someone else actually has one running, but thinks it's too ugly to
give out right now. (I haven't heard from him in some time, though. In
fact, I've forgotten his name. He was working on the NT port of Majordomo.)
Also, Smartlist has some logic used to trap the more common cases which
might be a good starting point.
In the end, though, for any such tool to be generally useful it has to have

The ultimate tool would keep a database of bouncing address and perform
different actions on those who give problems frequently.
In any case, a tool like this, even one that only works on something like
