Bias-Free Language

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.

    Introduction

    This document describes frequently asked questions about SenderBase.

    What is SenderBase?

    The SenderBase Reputation Service (SBRS) provides an accurate, flexible way for you to reject or throttle systems suspected to be transmitting spam based on the "reputation" of the connecting IP address associated with the remote host. The SBRS returns a score based on the probability that a message from  a given source is spam, ranging from -10 (certain to be spam) through 0 to +10 (certain not to be spam).  Although SBRS can be used as a stand-alone anti-spam solution, it is most effective when combined with a content-based anti-spam scanner, such as Cisco Anti-Spam.
