[ERROR] Email on another server > being delivered to localhost

I'm trying to send email from wordpress domain.xxx to info@domain.xxx. This mailbox is on another server. However, it is being delivered on localhost, where the mailbox does not exist.

How can I fix this, so that emails to info@domain.xxx are being routed correctly?

Access to your myphpadmin, as ROOT and open "postfix" database.
Go to "Domain" table and remove your domain that is being seen as local
