The following Domain RBLs started issuing a lot of false positives and have now been disabled from our system:
The false positive results also appear to be showing on the RBL’s website when using their web lookup form.
For the time being, until this issue gets sorted out by the RBL administrators, we’ll keep these RBLs disabled on our system.
If any of your domains appear as being blacklisted on the RBLs mentioned above, they will be marked as being delisted after the next automatic checkup.
