What it means
The Yahoo account you are sending to does not exist, so the message is permanently undeliverable.
Why it happens
- The recipient address is invalid or misspelled.
- The account has been closed or moved.
How to fix it
- Contact the recipient directly to confirm their correct email address.
- Do not retry delivery, because it will never complete successfully.
- Remove the address from your mailing list.
- Double-check the spelling of the address, since a single misplaced letter can cause the failure.
