Please Help, completely confused
1. I can't send out email with 553:domainname server does not exist returned by outlook express yesterday.
2. I tried to use web hosting company's webmail yesterday, it can't send out email with error:
Error sending message:
MAIL first (#5.5.1)
3. Today, I even found my website down.
I contacted my web host, they said it is due to
domain name is not resolving to your account on our servers
The web host also said when they look into whois database, they saw our domain name present and registered, and pointing to their server correctly.
They said they can confirm that their server has no problem, and therefore it is a DNS root level problem. (I don't know what it is)
I am also asking the domain registrar to look into the issue without getting reply.
Anyone knows what's the problem? and how can I solve it?
Please advise.
