Designate untrusted and trusted email domains

Designate specific email domains as untrusted or trusted so that you can monitor the metrics for incoming emails from these sources in your instance.

Before you begin

Role required: security_dashboard_user or admin

About this task

When untrusted or trusted domains send emails to your instance, their daily counts appear on the Untrusted Incoming Email or Trusted Incoming Email metrics on the Email page. You can then track email activity from these domains and use email logs to view specific incoming emails. You can also specify a user, usually a manager, or a security analyst, to notify whenever activity occurs from the untrusted or trusted domain.
Note: Designating an email domain as untrusted is for security tracking purposes only. It does not prevent delivery of emails sent from the domain to your instance. To learn about filtering emails to block their delivery, see Email filters.

Procedure

  1. Navigate to System Security > Instance Security Center.
  2. On the Instance Security Center homepage, click the Email tile, or click the Email link to access the Email page.
  3. On the Email page, in the Untrusted And Trusted Domain section, click New.
