The official way is that the "Return-Path" header will be empty (or missing)
so that recursion will not occur for error messages that themselves cannot
be delivered. In theory, it should not be possible for a normal message to
have an empty "Return-Path" header, since it is automatically added by the
server that delivers the message.
