Not able to receive emails to mydomain emails, where as i am able to send

What panel are you on?

Hi,i am having new panel

@Imahat So you’re using email feature available on your domain panel?

If yes, then you should cname instead of nameservers to point towards 000webhost.

Yes i am using email feature in my domain panel. Please let me know more detail how to do it

@Imahat So instead of using nameservers to park your domain use cname to point towards 000webhost.
Why cname because to have full domain dns control.
Why not nameservers because it doesn’t allow to have full domain dns control.
By using “cname” you can use domain panel email feature.

If you have already parked your domain using name servers, then…I would suggest use “Email Forwarding” feature available on the new panel.
