anonymous(_at_)[127(_dot_)255(_dot_)255(_dot_)255], anonymous(_at_)[::0], and

These might be OK in the message header. In the envelope they are likely
to be rejected as invalid, because many sites put restrictions on the use
of domain literals, and checks on envelope addresses tend to be more
thorough. In addition to that, many sites reject domains that do not refer
to globally routable addresses.
