Unable to send emails to club addresses

Hello
I am unable to send email to the club email addresses like members@<clubname.com> or president@<clubname.com>. I get Delivery Status Notification (Failure) stating that Address was not found.

The exact error is:
Your message wasn't delivered to secretary@jewelcity29.com because the address couldn't be found, or is unable to receive mail.

The response from the remote server was:
