When search email logs in Email DLP admin console, the email has been filtered under the rule [フィルタリング適用対象外 (Not applied by any filtering)]. What does this rule mean?
In the case that the email does not match any rule, it will be automatically passed through this rule which will just send the email out directly.
In addition, there will also be email logs with the rule name specified as [最初のチェック（HDE管理）]. These are displayed as a constant check made by HDE Email DLP service. Please ignore the logs.
