Hey there! This log entry shows the message is trying to be delivered locally on your server. Is that the correct action? If so, the email account doesn't exist.

If the mail should be sent to an external account, you'll want to check the cPanel >> Email Routing option to get that configured for remote delivery.

Hi, I also noticed that and it turns out that the domain is hosted somewhere where we are trying to send email and also added in Addon domains. That's the reason it was going locally instead of going remotely.

Thanks, the issue is resolved.
