The Gmail Scope configuration page allows you to set filters to perform the following tasks.
Monitor or Exclude Monitoring of Emails sent by Specific Users and Groups: You can set up the Gmail scope to monitor only the required emails that were sent by either specific users or from a user group ID. Similarly, you can also choose to exclude certain user and group mail IDs from being monitored.
Monitor or Exclude Monitoring of Emails sent to Specific Recipients and Domains: You can choose specific email IDs that you wish to monitor or skip monitoring.
The Scope section is divided into the following two sub-sections.
Senders: Select this option if you wish to monitor or exclude monitoring of outgoing mails from specific users or user groups.
Recipients: Select this option to monitor or exclude monitoring of emails sent to specific recipients. The recipients can be a user or a user group. Additionally, you can also choose to exclude an entire domain. All the emails sent to the mail IDs of the excluded domain(s) are not monitored by Nightfall.
Exclusions are evaluated before inclusions
Recipient filters are validated before the sender filters
User-level filters take priority over group-level filters
Domain-level filters, for recipients, have the highest priority
If no filters match, the default action is to scan the email
Important
The following list represents both the order and priority in which filters are evaluated when multiple filters are configured in a policy. Filters higher on the list take precedence over those lower down.
Recipient Domain Exclusions
Recipient Domain Inclusions
Recipient User Exclusions
Sender User Exclusions
Sender Group Exclusions
Recipient User Inclusions
Sender User Inclusions
Sender Group Inclusions
Default to scan all emails, if no other filters apply
Now, let's take a look at an example scenario to describe the behavior.
Example Scenario:
A marketing team member (sender@company.com) sends an email to:
Let's examine how different filter configurations would affect this email:
Recipient Domain Exclusions:
If configured: external-partner.com is excluded
Result: Email will still be scanned because not all recipients are in the excluded domain.
Recipient Domain Inclusions:
If configured: external-partner.com is included
Result: Email will be scanned given one of the domain is included.
Recipient User Exclusions:
If configured: ceo@company.com is excluded
Result: Email will still be scanned because not all recipients are excluded.
Sender User Exclusions:
If configured: sender@company.com is excluded
Result: Email won't be scanned, regardless of recipients.
Sender Group Exclusions:
If configured: Marketing group is excluded
Result: Email won't be scanned if sender is in the Marketing group.
Recipient User Inclusions:
If configured: team@company.com is included
Result: Email will be scanned because at least one recipient is included.
Sender User Inclusions:
If configured: sender@company.com is included
Result: Email will be scanned due to sender inclusion.
Sender Group Inclusions:
If configured: Marketing group is included
Result: Email will be scanned if sender is in the Marketing group.
Default to scan all emails:
If no other filters apply, the email will be scanned.
Notes:
The first matching filter as per the priority listed above determines if the email is scanned.
For recipient-based filters, ALL recipients must match for exclusions, but ANY match triggers inclusions such that the email is scanned.
This priority order ensures that the most specific and restrictive rules are applied first, allowing for precise control over email scanning while maintaining a clear hierarchy for conflict resolution when multiple filters are in place.
