qbonkns is an extension of qbonk.

It searches the queue for messages with no sender address, does a "qbonk" on
them, and then does "qkick" afterwards. This deletes spam-bounces which
otherwise would just sit in the queue until they time out on their own. One of
my ISP clients runs this as an hourly cron job on their servers...
