I think that one's been since fixed. None of the Moderation.py checks
are done on messages from NNTP. Some of the Hold.py checks are still
done (all but the explicit destination check).

I agree that it would be nice to have more control over which checks are
done based on the origin of the message. That's more of a feature
request for future versions though. But try it again, because Mailman
2.1.3 should be applying mostly the right checks for gated messages.
