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
