That is odd. Here, roaringpenguin.net does not resolve at all. And
209.195.84.23 still resolves to roaringpenguin.com. In fact, your latest
response came from that address:

Received: from www.roaringpenguin.com (roaringpenguin.com [209.195.84.23])

And I still cannot find 209.195.84.23 being listed anywhere as MX record for
roaringpenguin.com.
