The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

This document describes how SenderBase can be used.
How do I use SenderBase?
You can use SenderBase in a number of ways.
At the SenderBase web site, www.senderbase.org, you can enter IP addresses and network ranges to research email senders, IP addresses, and sources of suspected spam as well as the IP addresses of your own mail servers.
Using DNS-based queries, the Email Security Appliance (ESA) can look up SenderBase scores for email senders and use those results to throttle, block, or "trust" senders.
Message filters running on the ESA can use the SenderBase score in any way allowed by the filtering language. For example, SenderBase scores can be tagged into message subjects or body headers, or they can be factored into filter actions with other information.
