I bought a domain without webspace and want to forward emails to that domain to my Gmail account. But I don't receive any emails which are send there, not even a return-to-sender-email. I also tried with another email provider and my company's email address.My hoster supports email forwarding, thus I activated it with the catch all option and added my 3 email addresses as target. The domain is configured with www IN CNAME example.rhcloud.com. There is no other configuration yet.Do I need to add MX entries? Or what else do I need to do?P.S.: Don't migrate this question to serverfault. They said I'm not allowed to ask questions, because I'm not a sysadmin...
How to forward emails to my custom domain to my Gmail account?

You will need to add an MX record to your domains DNS. If you're using your Registrar to do the email forwarding, you'll add their e-mail servers for the MX records. Without an MX record, mail servers have no idea which servers to send the mail to.
