When sending email I receive "Relay Access Denied" errors.
If you are receiving "Relay Denied" errors, please ensure to check the box next to "My Server Requires Authentication" in your Outgoing SMTP preferences. This will enable "SMTP Authentication" and ensure you do not receive any "Relay Denied" errors.
