that pipeline, but it probably isn't feasable to use
header_filter_rules for this as the same rules apply to list posts,
but you could implement a simple custom handler to discard any message
that didn't have a message-id of the form generated by mailman or a
mailman-like envelope sender or from address and add that to the
