      Nothing in Postfix generates an "Unknown user" response of any kind
      (the string "Unknown user" does not appear in the Postfix source
      code). Even such a string were returned it would not be with a
      "5.7.1" DSN code, which indicates site policy not address validity.
      Perhaps you have a milter or policy service that generates this
      response.
