Incoming email error 550 - Relay not permitted
If you experience the problem described in the title and the description of this article, it most likely means that your domain is hosted with us and has the correct name servers, but our system has not verified the name servers yet. This would usually happen with domains, which have been recently added to the Hosted Domains section of your Web Hosting Control Panel.
When you add a domain to your Hosted Domains to be hosted in your account with us, at first there is a red X sign in the DNS column indicating that the name servers of your domain are not correct. This would also happen with domains, which actually have the correct name servers because it takes up to several hours for our system to verify the name servers of your newly hosted domain. Once the name servers have been verified you will be able to see that the name servers are correct - there will be a check-sign (V) in the DNS column for your domain in the Hosted Domains section.
Back to the problem with receiving emails: It will be resolved, once our system has verified your domain's name servers. If it takes more than 12 hours you should contact us by opening a support ticket. We would be able to force the system to check your domain's name servers.
Before you contact us, however, please make sure that your domain is in fact using the correct name servers. For further information about the name servers, which you must apply to your domain to be properly hosted, please refer to: What are the correct name servers (DNS) for my domain?
Also, please be informed that it takes 12-24 hours after you update your domain's name servers before the change takes effect.
