GoDaddy Email delivery response
GoDaddy Email 550 5.7.1: Relay access denied
GoDaddy documents this response when the server will not relay the message. Confirm the outgoing server and authentication first, then check SPF, DKIM, and DMARC only when the complete bounce names domain authentication.
A representative response is:
550 5.7.1 Relay access denied
Run this automated test on my domain
Enter your domain. MailFixIt checks the relevant DNS records automatically and shows the evidence.
Treat this as permanent until the complete provider response and retry behavior show otherwise.
Check the route first
- Confirm that the client uses the outgoing server GoDaddy specifies for the mailbox product.
- Enable SMTP authentication and use the complete mailbox address as the username.
- Confirm that the From address is allowed for the authenticated account.
- If the bounce explicitly names SPF, DKIM, or DMARC, check that named record.
Verify the fix
Send one message through the corrected route and keep its SMTP log. Do not add broad SPF authorization just to clear a relay error; SMTP credentials and relay permissions are not controlled by SPF.
MailFixIt scope
MailFixIt can inspect public authentication records when the bounce names them. It cannot test the mailbox password or change GoDaddy relay permissions.
Frequently asked questions
What does GoDaddy Email 550 5.7.1 Relay access denied mean?
The server refused to relay the message. Wrong SMTP settings or missing authentication are common causes; some GoDaddy guidance also associates this response with domain authentication.
Can MailFixIt prove this entire bounce from public DNS?
No. The current checker can evaluate selected public DNS configuration, but it cannot recreate recipient state, credentials, reputation, message content, or a historical provider SMTP decision.
