    Test your setup at, and post the "bad" results here (if any)
    Enter your URL in the DNS report box!

    I test using DNS Report and this is the Fail and the Warn Items

    Missing (stealth) nameservers[/B][/B]
    FAIL: You have one or more missing (stealth) nameservers. The following nameserver(s) are listed (at your nameservers) as nameservers for your domain, but are not listed at the parent nameservers (therefore, they may or may not get used, depending on whether your DNS servers return them in the authority section for other requests, per RFC2181 5.4.1). You need to make sure that these stealth nameservers are working; if they are not responding, you may have serious problems! The DNS Report will not query these servers, so you need to be very careful that they are working properly.
    This is listed as an ERROR because there are some cases where nasty problems can occur (if the TTLs vary from the NS records at the root servers and the NS records point to your own domain, for example).

    Missing nameservers 2 ERROR: One or more of the nameservers listed at the parent servers are not listed as NS records at your nameservers. The problem NS records are:

    Stealth NS record leakage Your DNS servers leak stealth information in non-NS requests:

    Stealth nameservers are leaked []!
    Stealth nameservers are leaked []!

    This can cause some serious problems (especially if there is a TTL discrepancy). If you must have stealth NS records (NS records listed at the authoritative DNS servers, but not the parent DNS servers), you should make sure that your DNS server does not leak the stealth NS records in response to other queries.

    MX is host name, not IP ERROR: You have one or more MX record(s) that contain an IP address. This is not valid. A fully RFC-compliant mailserver will not be able to send you mail (although some mail servers will, due to the TCP/IP functions that they use). The problem MX records are:

    The last fail (MX is host name, not IP ERROR) could be your problem!
    Try fixing it, and see if it fixed your problem

    Ok i see this , From My Control Panel i see that my MX record is the IP of my Mail server.
    I will tell MY Web Hosting Company to Add new (A) record for my mail server Then I will change the MX to FQDM and .
