    Edit DNS Zone Subdomain MX Records

    I'm having a very strange problem with an client and it seems to have something to do with this.

    They have their root domain of ""
    They created a sub-domian of ""
    They pointed the CNAME for "" over to an address.

    They also want to use Gmail for the sub-domains email so they added in the following MX entries into Cpanel

    register        7200    IN      MX      1       ASPMX.L.GOOGLE.COM.
    register        7200    IN      MX      5       ALT1.ASPMX.L.GOOGLE.COM.
    register        7200    IN      MX      5       ALT2.ASPMX.L.GOOGLE.COM.
    register        7200    IN      MX      10      ASPMX2.GOOGLEMAIL.COM.
    register        7200    IN      MX      10      ASPMX3.GOOGLEMAIL.COM.
    Up to this point everything looks fine however DNS doesn't seem to be loading the MX records when I do a dig lookup. In fact I get the following

    # dig MX
    ;          IN      MX
    ;; ANSWER SECTION:   961     IN      CNAME
    ;; AUTHORITY SECTION: 43 IN SOA 1337968855 3600 900 7776000 60

    # dig
    ;          IN      A
    ;; ANSWER SECTION:   1800    IN      CNAME 60 IN A 60 IN A 60 IN A
    ;; AUTHORITY SECTION:      2089    IN      NS      2089    IN      NS      2089    IN      NS      2089    IN      NS      2089    IN      NS      2089    IN      NS      2089    IN      NS      2089    IN      NS
    ;; ADDITIONAL SECTION:   9962    IN      A
    Why or how is it over riding the DNS AUTHORITY SECTION and putting Amazon's NS servers in there? That should be the DNS server of ''.

    Below is the root domain's '' info.
    # dig
    ;                   IN      A
    ;; ANSWER SECTION:            74      IN      A
    ;; AUTHORITY SECTION:            19874   IN      NS            19874   IN      NS
    ;; ADDITIONAL SECTION:     50653   IN      A     53053   IN      A
