Endpoint settings: the Email Domains tab

Use the Email Domains tab of the Settings > General > Endpoint page to configure email monitoring.

This includes defining which directions may be monitored for endpoint email (for instance, only outbound). The direction or directions that are actually enforced are determined by the settings on the Destination page of a custom rule.

In the rule, if you choose a direction that is not allowable per the Email Domains setting, endpoint email traffic is not analyzed.

To configure email monitoring:

Steps

  1. Under Internal email domains, use the Domain field to enter each internal domain used by the organization. These are domains from which users in the organization can send email.
    • Click Add to add each domain to the internal email domains list.
    • To delete an existing domain from the list, select the domain and click Remove.
      Important: Do not leave the domain list blank. When there are no entries in the list, endpoint email is not analyzed.
  2. Select Outbound to monitor traffic between a source domain defined in the Internal email domains list and any destination domain that is not in the list.
  3. Select Internal to monitor email traffic between source and destination domains that are both in the Internal email domains list.
  4. Click Save.
