Viewing Matched Content

When you configure a quarantine action for messages that match Attachment Content conditions, Message Body or Attachment conditions, Message body conditions, or the Attachment content conditions, you can view the matched content in the quarantined message. When you display the message body, the matched content is highlighted in yellow, except for DLP policy violation matches. You can also use the $MatchedContent action variable to include the matched content from message or content filter matches in the message subject.

If the attachment contains the matched content, the attachment’s contents are displayed, as well as the reason it was quarantined, whether it was due to a DLP policy violation, content filter condition, message filter condition, or Image Analysis verdict.

When you view messages in the local quarantine that have triggered message or content filter rules, the GUI may display content that did not actually trigger the filter action (along with content that triggered the filter action). The GUI display should be used as a guideline for locating content matches, but does not necessarily reflect an exact list of content matches. This occurs because the GUI uses less strict content matching logic than is used in the filters. This issue applies only to the highlighting in the message body. The table that lists the matched strings in each part of the message, along with the associated filter rule, is correct.
