I totally forgot about that rule set. But my issue here is not
backscatter. On low scoring spam, we notify the sender for some domains.
For those that get a large volume of low scoring spam, I'd rather move
those messages into a low priority queue and have them serviced less
frequently while important messages are routed to the next hop MTA.

Thanks Julian!
