"Modify" actions change the message or its attachments. The original sender will still receive the modified message, assuming that the message does not trigger other rules with "Intercept" actions.
Note:
Note that the "Modify" actions may destroy the existing DKIM signatures in email messages. If this occurs, the messages cannot pass DKIM verification by the downstream mail server.
