Cannot receive Email

Hi,

I have not been able to receive any emails on my email id. I tried sending an email from my personal email id and the following error message pops up: 

"DNS Error: 3476754 DNS type 'mx' lookup of kosmos.net.au responded with code NOERROR 3476754 DNS type 'aaaa' lookup of mail.kosmos.net.au. responded with code NXDOMAIN 3476754 DNS type 'a' lookup of mail.kosmos.net.au. responded with code NXDOMAIN"

 

Any help to fix this issue will be appreciated. 

Thanks guys.
