Nothing can escape a black hole, that's why these lists are called "blackhole" lists.
Honestly, I have not come across a solution to catch all such mail. The major reason is that one job of blackhole lists is to reduce the server load by keeping unwanted mail away from any subsequent process. If you want to receive such mails, it does not make sense to use a blackhole list, instead you can then simply configure catch all addresses for your domains.
