    • To import senders and recipients in pairs, click Import on the tab.

    • To import senders for a specific recipient, click a recipient name, and click Import in the dialog box that appears.

  3. From the import dialog box, click Choose File to locate the file to import.
  4. Select one of the following import options:

    • Merge: append the sender email addresses or domains to the existing list.

    Trend Micro Email Security checks all the entries in the selected file to identify any invalid, duplicate, conflict, excessive email addresses or email addresses from unmanaged domains.
