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. Tuc/TBOH
