Infrastruktur

I created a ticket with the hosting provider and still waiting for a reply.: https://my.hostbrr.com/plugin/support_manager/client_tickets/reply/25825/.

I got reply (attached).

Regardless of the response, I found a workaround by changing the submission mail server to dasg1.hostypanel.com instead of mail.nawan.my.id, and it seems to work. Hence close this issue.
