incoming emails not working

Hi,
I have a business internet from comcast, i can send email with no problem, however when i try to receive emails i get the following error:

Technical details of permanent failure:
DNS Error: 7960633 DNS type 'mx' lookup of mydealexpress.com responded with code NXDOMAIN
Domain name not found: mydealexpress.com

these are my dns settings, is something wrong in my dns settings?

Check your domain with www.intodns.com - you have some problems with your namesevers at the parent level

 

thank you for your response. I checked intodns but it does not show any problems there.

 

Really? It shows "nothing" for mydealexpress.com - and this is a problem. Are you sure, that your server is the authoritative dns-server for this domain?

 

yes but now its working, maybe it took time for the parent dns to set in properly.

 

i used godaddy as the authoritive dns for this server because somehow mine is not working properly. with godaddy its working fine. dont know why
