[January 1, 2018]
The ‘rbl.iprange.net’ RBL has started issuing false positives, showing every IP as being blacklisted.
We have now disabled this RBL in our system and we will continue to monitor the situation.
You may safely ignore any notifications that your IPs have been blacklisted or delisted by this RBL.
