Yes, this is correct.

Yes, I have compared the headers of test messages in detail. Didn't see
anything wrong or suspicious in them. In fact they look very similar to
our internal headers.

Yes, the test rule fires 100% in that case.

Yes, I have looked at those logs a lot. No errors or warnings or anything
else that might indicate what is going on.
