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, email accounts and email aliases from Open LDAP, Microsoft Active Directory, Microsoft AD Global Catalog, 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
    • Downloads: Displays the download paths or links to the Directory Synchronization Tool, Directory Synchronization Tool User's Guide, REST API Client, and REST API Online Help.

    • Synchronization Summary: Displays the total number of email aliases, groups, and valid recipients last synchronized from all directory sources.

    • Synchronization History: Displays the number of email aliases, groups, and valid recipients synchronized each time.

  • Directory Import

    • Import User Directory: Selections for importing a new user directory file.
