	Just a note to let everyone know its all working again. I was
escalated to someone else in RR and intelligent things came out of their
mouth and its not an issue anymore.

	The initial responder at RR needs a clue, and the bind-users said
I was doing something "moderately bad" at the same time. I'm working out
a tactic to resolve my bent-clue issue. I hope to have that fixed in a
week or so. RR is now accepting my mail despite my "bent clue" and one
DNS server being down.
