This RBL has started issuing false positives. We have temporarily disabled it until the issue is fixed on their end.
Looking at the RBL’s domain, it seems that ICANN has suspended it for non-completion of their contact verification.
Even though we caught this issue quite early on, some monitors may still appear as being blacklisted on this RBL now. This can be safely ignored and it will be fixed after the next automatic check of your monitors.
