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.
