Number of Email Destinations
Messages sent to multiple destination domains may indicate spam.
Specify the number of destination domains to detect. Email messages sent to this number of domains (or more) trigger the policy. The default number of domains is 25.
Also, select which email fields to monitor—the To field (To), copy field (Cc), or blind copy field (Bcc). To and Cc are selected by default.
This option applies to outbound email only.
