Bind unable to get MX reocrd from Parrent name server

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

Re: Bind unable to get MX reocrd from Parrent name server

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. Steve On 5 July 2013 12:35, Fosiul Alam fos...@gmail.com wrote: Hi
