If you are using or collaborating with other users via Google Docs, you may notice that some users get flagged as Individual Display Name Imposters (IDNI). This is due to how Google uses the display name for comments and documents, and who is added to your Address Groups.
From time to time you may see messages where a user in your address group is in the display name of a notification message when they make a comment on a shared Google Doc. This can trigger some of your Imposter policies. As you can see in the below example, Armen Najarian is in the Executive Address Group, but this message has his name in the "friendly-from", and not coming from the Agari domain, thus triggering the policy.
To resolve these Fales Positives, simply add <firstname.lastname@example.org> to your Address Group Exceptions list. Navigate to Manage > Address Groups, edit the group in question, and add the sending email address to the Exceptions section.
Going forward, new messages that come in will show as a BDNI Exception in the scoring reasons.
