Automated RBL Check

Not crazy, but LM has a limited communication channel for problems.  Would be best if event sources could do it, but really not well suited due to inability to acknowledge (no correlation across checks).  If a DS was used, could program the list as instances and at least then know what triggered.  Ideally it would be a preset list, but one that is adjustable.  I am not aware of any way to do that (hybrid AD and manual instance definition), so it may require fully manual definition of the list, or AD with an external instance fetch (e.g., JSON source).
