RBL reputation analysis votes on the probability that the message is spam based on comprehensive information about the source of the message, rating the reputation of the sender based on the percentage of spam messages sent from that IP address in the past.
Sentinel Messaging assigns a level of trust to key real-time blackhole lists (RBL) that rates the reputation of the RBL based on its accuracy at blocking spam. While most service providers use RBLs, Sentinel Messaging also provides a customer-configurable process for limiting false positives to help ensure that our customers receive a high level of spam protection with minimum impact on their businesses.
