Adding MX Records

We are a school system that uses GMail for our domain. We have a sub-domain called and we are finding that we are not able to send emails to that domain. the error we are receiving is this:

Address not found
Your message wasn’t delivered to " " because the domain ( couldn’t be found. Check for typos or unnecessary spaces and try again.

Today I added an MX record for the domain but still can’t send to that address. Any thoughts are welcomed.

-Bob is on Cloudflare, but there is seemingly no record for k6.

Is your intention to receive emails under “”?

Yes, some of our student accounts will be [email protected].

In that case you will need to create an MX record for “k6” and point it to the respective SMTP server.
