The list of RBLs we monitor at any one time can vary, as RBLs come and go on a regular basis. Our base list of RBLs are chosen for their reliability, and their overall confidence in the community.
That being said, just because we don’t include an RBL on our default list, doesn’t mean you can’t use it.
All paid accounts come with the ability to add as many custom RBLs to you account as you would like. If we don’t currently offer an RBL that you’d like to use- no problem- just add it via our Portal.
To find the current list of data sources we use to monitor hosts, click the “Data Sources” link on your Monitoring Profile from the Manage -> Monitoring Profiles section of the portal.
