Down is there isn't power to it until it gets repaired. So its not answering period. A "nslookup" shows "timed-out". A "dig" shows "connection timed out; no servers could be reached" (When querying ONLY against the down server).
So how do I go back to RR, who told me to take it out of my NS records, that DNS is supposed to be silently falling back and trying again?
The fact that they're rejecting on a 5xx error based on no DNS PTR is a bit harsh. While I'm all for requiring all hosts to have valid PTR records, there are times when transient or problem servers can cause a DNS lookup failure or miss, etc. If anything they should be returning a 4xx to have the remote host"try again later".
Robert,
Sorry, they aren't giving a hard fail. Its a soft fail, so we'll retry. But after 5 days of retrying, my servers will give up. (And, in the mean time, the mail isn't getting through, so my users are without mail {We store/forward for them} I don't know if the down (hard) server will be back that soon (Its been 2 days as is). But the whole POINT of DNS is I have a 2nd one listed, and they don't seem to care. They are telling me that they want my "primary" one back up and running.

I know this is strange for nanog but if you actually stated the IP addresses of the mail servers we could look to see if there is a problem other than what you think the problem is.
You havn't stated it here or on bind-users

Hi, 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. Tuc/TBOH
