Logwatch keeps sending this every night:
Zone update refused:
184.108.40.206 (domain.com/IN): 77 Time(s)
"Domain" is my clients, and the connecting IP is on the Roadrunner network it seems. The count always seems the same. It's the only update I seeing attempted and refused, and I can't help but wonder whats going on here. Why would RR (or someone on it) be trying to update a zone on my box? It was never hosted with them in any way, and I was the original registrant for the client's name.
They ("domain") have an internal network (but the provider at their location is Adelphia, not RR), and recently asked me why their site wasn't showing (they were still looking for it on the old box, despite several notifications about the move), so they are keeping thier own zone records it would appear.
