How to fix Email DNS related Error called ‘550: relay not permitted’.

You may encounter this error, ‘550: relay not permitted,’ if your remote email server is misconfigured on your web/email hosting service. You may also encounter this issue when you misconfigured your Cloudflare account’s DNS settings.

The main symptom is that you cannot receive emails using your email ID.

So, how do we fix this?

The solution is simple!

There are two records needed to correctly point your Email Hosting Service Provider. A ‘MX’ record and an ‘A’ record. A MX-record points to the domain and the A-record for said domain points to the right IP address provided by your email service provider e.g

Note: For example, I am using Cloudflare’s DNS settings to correctly point to the right Email Hosting Service Provider.

‘MX’ Record 10′ ‘’

‘A’ Record ‘mail’ ‘’

I hope this information helps you resolve the ‘550: relay not permitted’ error in your mail server settings.

Thanks & Regards
