    Case sensitivity

    Case sensitivity

    Regular expression pattern matching in FortiMail is case insensitive. For example, bad language blocks bad language, Bad LAnguaGe, etc.Therefore, the regular expression /i, which may be used to make a word or phrase case insensitive in other products, should not be used in the FortiMail configuration.
