When mail is undeliverable, how shall this filter send the
non-delivery notification?

In fact, you can use empty_address_default_transport_maps_lookup_key
for explicit handling of the null sender.

That depends on how you specify the filter and how the bounce
arrives. If the bounce arrives via SMTP, you can specifiy a different
filter for the null sender, or override the content_filter parameter
setting.
