About Directory Management

You can import LDAP Data Interchange Format (LDIF) or comma-separated values (CSV) files into Hosted Email Security. This helps Hosted Email Security to better filter and process messages for valid email addresses. Messages to invalid email addresses will be rejected.

Hosted Email Security uses user directories to help prevent backscatter (or outscatter) spam and Directory Harvest Attacks (DHA). Importing user directories lets Hosted Email Security know legitimate email addresses and domains in your organization.

Hosted Email Security also provides a Synchronization Tool that enables you to synchronize your current groups and email accounts on the ActiveDirectory server with the Hosted Email Security server.

The Directory Management screen includes the following tabs:

  • Directory Import

    • Import User Directory: Displays the selections for importing a new user directory file.

    • Imported User Directory History: Displays the imported user directory file(s) that Hosted Email Security is using.

  • Directory Synchronize
    • Synchronization Summary: Displays the number of valid recipients and groups synchronized using the synchronization tool.

    • Synchronization History: Displays the last seven (7) days' synchronization history.
