Relay Access Denied
Also known as: 554 5.7.1
"Relay Access Denied" is a common error message indicating that a mail server refused to let you send email through it because you are not authorized.
"Relay Access Denied" (often error code 554 5.7.1) happens when you try to send email through a server that doesn't recognize you or hasn't been configured to trust you.
Email servers are generally set up to only accept mail for their local users (incoming) or from authenticated users (outgoing). If an unauthenticated user tries to send mail through the server to an outside address, the server blocks it to prevent being used as an "open relay" by spammers.
To fix this, ensure you are authenticating correctly (using a username/password or IP authorization) with your SMTP server, or that "SMTP Authentication" is enabled in your email client settings.
