I agree. There is no black-list that I would use, except internal
ones, to outright reject emails. They all contribute to the spam
score. This unfortunately creates more traffic as all lists are
queried. This can be mitigated by checking the cumulative score
before performing successive checks and stopping when the spam score
threshold for the recipient has been reached. A random rotation of
blacklists should also be implemented.
