Cant send email to my sub account

When I try to send a email to my sub account, I receive this error response. Along side this issue I cannot receive any emails from anyone else. They send out fine but can not receive any in return.

550 5.2.1 <subname>... blank mailhost - invalid address, relay=[209.85.218.49]

Here to help with your email, @whateverjaxonjr

Are you using a mailing app or a web browser?
Have you tried troubleshooting your email?
Have you tried resetting your password?
Are you using an email client that is compatible with OAuth or are you using a Secure Mail Key?

We recommend these things as resetting your password will resync your email and troubleshooting your email will resolve minor concerns regarding your email.

If you are using an email app we recommend setting up a Secure Mail Key or Oauth as this is a security feature that is required on most apps.

Let us know if this helps!
