    Just need to know what the answer to this was, it was a question in an interview, I still have no idea how to solve it....
    Thanks for helping me understand..

    A customer has setup a domain and website (abc.com) on their VPS and is trying to get mail for that domain routed to that VPS. The domain uses the provider ’s name servers, and the MX record for the domain is:

    Hostname mail
    Type (IN) MX
    Content mail.abc.com.
    Priority 0
    TTL 600

    There is a corresponding ‘A’ record pointing the hostname ‘mail’ to the VPS’s IP address. If you query the provider name servers directly (using dig or nslookup for example) for the MX record for ‘abc.com’, you don’t get any returned records. If you query ‘mail.abc.com’ you get the IP address of the VPS as expected. Explain to the customer what they need to change about the MX record to get it working as intended.

    Thank you!!

    Hi BD,

    Thanks for posting here.

    Creating an new A record with empty host name and point to the IP address of VPS under abe.com on provider ’s name servers so we will get a record with name “(same as parent folder)” . After that please creating a new MX record with also empty host name and “Mail.abc.com” as the FQDN of mail server under same zone on DNS server .

    Thanks.
