Directory Management

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

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

Trend Micro Email Security also provides a synchronization tool that enables you to synchronize your current groups and email accounts from Open LDAP, Microsoft Active Directory, Microsoft AD Global Catalog, Microsoft Office 365/Azure Active Directory and IBM Domino servers to the Trend Micro Email Security server.

The Directory Management screen includes the following tabs:

  • Directory Synchronize
    • Synchronization Authentication Key: Displays the Synchronization Authentication Key, which is a global unique identifier for your Directory Synchronization Tool to authenticate its access to Trend Micro Email Security.

    • Downloads: Displays the download paths for the Directory Synchronization Tool and Directory Synchronization Tool User's Guide.

    • Synchronization Summary: Displays the number of valid recipients, groups and email aliases synchronized using the synchronization tool.

    • Synchronization History: Displays the synchronization history.

  • Directory Import
