Thank you for the clarification.

It's hard enough to recognize all the various non-compliant messages
which are actually bounces of list mail and extract the bouncing
address(es) from them.

While I sympathize with the problem of autoresponders replying to the
list or the list-bounces address, to try to actually recognize such
messages as what they are and attribute them to the actual list member
is a task too daunting for me to consider.

For autoresponses to the list, you could use header_filter_rules to
match things like auto-submitted or auto-replied and discard such
messages, but that won't work for messages to the -bounces address.

You can chose to forward such messages to the list owners or ignore
them, but to ask Mailman to determine the responsible list member and
score a bounce is more than I'm willing to try to do.
