ปัญหา

Generic email error response received when attempting to send email messages

วิธีแก้ปัญหา

This message indicates that you have sent a message too soon after a major DNS change.

DNS changes take 3-24 hours to propagate across the Internet. If you were to make a major DNS change, then attempt to send an email, the receiving server may not recognize your new domain. If the new domain doesn't exist in it's DNS (which is still propagating across the Internet), then it will reject the message with the error Sender address rejected: Domain not found.
