The email address was rejected.  Probably the XXXXX name.  Most spam
filters will reject email with multiple X's in the account name because
that is often spam or an attempt to hide the identity of the sender.

If both are yours, and their spam filter was not the reject cause, you
may discover that the registry had not yet fully propagated over their
network of servers, and so a few minutes or days later it might work.
