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 how to exclude words when using dictionary Message Filters.

On the Cisco Email Security Appliance (ESA), when using a dictionary match filter, you may need to exclude certain phrases that contain words in the dictionary.

The solution is to set up a message filter as follows:

if (dictionary-match("dictionary1") AND (not(dictionary-match("exclude_dictionary2"
)))) {quarantine('Policy');
}


The effect of this message filter is that it will catch any words that are listed in 'dictionary1' but it will deliver any message that contains words in 'exclude_dictionary2'.

The only drawback to this is if a message contains words in both dictionaries, then the message will get delivered.
