Hello,
mailer daemon gives me this error: “no valid MX hosts found”.
e-mail registration does also not work on my website.
What can I do?
Use premium https://www.hostinger.com/special/000webhost?utm_source=000webhost&utm_medium=frontend&utm_campaign=moderator
Or you can mess about with scripts and other free services to try and get it working.
etc
To complex to built that in.
