I just wondering why you block with temporary error? When you'd block with 5xx Error the customer would be informed after he sends the mail that it wasn't delivered... With 4xx Error he knows not until approx 4 days after he sent the mail. That seems not to good in my eyes...
In this case it's actually very good. A 5xx reject in this case would have caused far more problems.
