With the MARID tests there can be two times-of-failure, depending on the tests

Some tests can only fail after the message has been received in the DATA phase

bounce.
You can still send 5xx after DATA. That would be far preferable to accepting
the message and then generating a bounce, especially since any PRA failure is
likely to be due to deliberate forgery (at least after the first round of bugs
are worked out of the SUBMITTER/PRA testing code).
