Yes, I understand what you're doing now. However, I think you should
modify the syntax. I don't think putting the ! before = really makes it
clear what's going on.

To be more consistent with Exim's other configuration entries, it should be

deny dnslists dnsbl.njabl.org=!127.0.0.3,!127.0.0.4

This would be treated the same way that Exim currently handles host
lists, address lists, etc. If the last entry in the list is negated,
then any non-matching result is implicitly accepted.
