You can view Impersonation statistics in either Inbound or Outbound mode. The dashboard's Impersonation widget cycles through a display of:
Current impersonation count graphed over the specified time interval, percentage of all accepted mails, and trend
Top sender IP addresses (for SMTP domains only)
Top recipients
Note
Impersonation statistics are also included in the graphs for Spam or Advanced Threats, depending on your configuration. For more information, see Message analysis policies.
Impersonation statistics are available for Inline with Hygiene, MS365 Native with Hygiene, and Google Workspace Native with Hygiene domains only.
