I am not the domain admin for rbcaa.co.za
I can see they have issue with their domain setup .
but what I want to know is :

mxtoolbox,introdns,google .. (Despite they have issue with their dns
setup for that domain (as you said) ) then why we cant ??
Thanks for looking into it .

Your glue is broken. You need to update the glue NS records in the
parent to reflect the actual nameservers that are authoritative for
the zone.
It also looks like you could have some data mismatch between zones
hosted on (ns1.yithosting.co.za + ns2.yithosting.co.za) and
(demeter.is.co.za + babylon.mitsol.co.za). Check that the zone data is
consistent across the nameservers.

Hi
Occasionally we see customer is complainning that we are not able to
resolve mx record when mxtoolbox or other website can resolve their mx
record .
If i do a trace on the domain, i get bellow .
now the problem is :
demeter.is.co.za. and babylon.mitsol.co.za does not know anything
about MX record of that domain. but if i query by using parent name
server ns1.yithosting.co.za. and ns2.yithosting.co.za , it returns the
mx record .
but mxtoolbox, introdns can resolve the mx record although they
complain the same that
The following nameservers are listed at your nameservers as
nameservers for your domain, but are not listed at the parent
nameservers (see RFC2181 5.4.1). You need to make sure that these
nameservers are working.If they are not working ok, you may have
problems!
demeter.is.co.za
babylon.mitsol.co.za
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:
ns1.yithosting.co.za
ns2.yithosting.co.za
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).
then why our bind is unable to resolve mx record ???
Thanks for the help
