The intentional routing of error messages to a black hole, or to an
address which causes them to bounce to the site administrator, is not
the action of a responsible list owner. If your list is generating an
unreasonably large volume of legitimate delivery error messages, then
there is a problem with your list and you, as a responsible list owner,
ought to be interested in resolving that problem, rather than burying it.
If you, as a list owner, are unwilling to handle the responsibilies that
come with list ownership, then you need to find a replacement who will
do the job right.
