I think because it is not allowed to use emails based on custom domains, just for your own security because it is possible someone hacks the server where you’re hosting your email.

I’m using GSuite, Surely it would do MX lookup?


This is a strange issue, so I did some testing.

You’re on point about the MX lookups, the mail validation does check if the domain name is able to receive email. But for some strange reason, the DNS resolvers on the client area server for some reason can’t resolve your domain name.

This has been fixed now and your email address should be accepted now.


I’ve been having weird DNS issues, especially with subdomains, some places don’t like it, I appreciate your help.


I don’t know what caused the default DNS resolvers to return an error response. My first guess was that your nameservers might be malfunctioning, but I wasn’t able to confirm that anywhere else. If other places report DNS errors too, that does support the nameserver theory.

The nameservers resolve fine, all other DNS places find it fine. It’s weird and needs more troubleshooting.
