I apologize for confusing the issue by saying they weren't. I didn't notice the aa flag wasn't set on the dig results. Like Mike Tansca, though, I'd like to know exactly what is happening here. It seems to me that it either should accept mail, or not accept mail (I don't know what the "right" behaviour is if you only have a non-authoritative result), but instead it accepts mail for a bit, and then stops.
