Strange, RBL checks stopped happening.  Turning on some debug revealed
that none of the entries in the Spam Lists file (spam.lists.conf) were
being found due to case mismatch.  Changing everything in
spam.lists.conf to lower case fixed the problem and RBL checks are
happening again for me.

My guess is that the following has something to do with this...

Other than that, the new version looks great.  Thanks for the continued
support of an awesome product.
