Agreed. I've raised the issue on Microsoft's support forum. I am told they are taking a look at it, but I have not received confirmation that this is a bug in Windows Live Mail:

Hmm, I just notices there is one more reply from the INN server following the GROUP reply. But I don't see a corresponding request from WLMail, so I'm not sure what this additional reply means.
Here's a summary of the whole exchange:
