Importing Recipients for Forward Mailboxes from a CSV File

Import recipients for forward mailboxes from a CSV file.

Instead of entering recipients for forward mailboxes manually, you can import them from a CSV list. This can be done both initially, before any data has been entered, and additionally during operation.

Note:

Forward mailboxes cannot be assigned to Microsoft 365 mailboxes or mailboxes synchronized via LDAP. Thus, no recipients for forward mailboxes can be imported from a CSV file for these mailboxes.

  1. Log in to the Control Panel with your administrative credentials.
  2. Select the domain from the scope selection.
  3. Navigate to Customer Settings > Mailboxes.
  4. Click on Add.

    A new form is displayed.

  5. Enter the email address of the forward mailbox under Email address.
  6. Click on Import list from CSV file.

    A file selection window opens.

  7. Select the desired CSV file.
    Important:

    To ensure that an external CSV file can be imported into the Control Panel without errors, special rules regarding the file format, the content structure as well as a valid syntax must be observed (see CSV Files for the Import of Recipients).

  8. Click on Import list from CSV file.

    The addresses from the CSV file are imported and displayed in the Forwards to section.

    Note:

    The following rules apply to the import of recipients for forward mailboxes:

    • Addresses that are already displayed under Forwards to are not deleted.
    • Only entries from the CSV file that are not already displayed under Forwards to are imported.
    • Duplicated entries from the CSV file are imported only once.
    • Incorrectly formatted list entries are ignored and do not lead to the termination of the process. However, after the import, an error message is displayed if invalid entries are present.
    • If the CSV file does not contain any valid addresses that are not already present in the Forwards to section, a corresponding error message is displayed and no addresses are imported.
  9. Click on Add.

You have imported recipients for forward mailboxes from a CSV file.
