To make it easier for daily changes to be noticed in the Blacklist Monitor Reports, the RBL list row background color may appear as:
White background – means no changes occurred for those RBLs since the previous day.
Green background – means the IP was listed on that RBL on the day before, but it’s not listed anymore during the current day.
Red background – means the IP was not listed on that RBL on the day before, but it’s listed on it during the current day.
