Can someone please help - delivery from outlook fails

Delivery has failed to these recipients or groups:

xxx@prodaja.ba (xxx@prodaja.ba)
Your message wasn’t delivered. Despite repeated attempts to deliver your message, the recipient’s email system refused to accept a connection from your email system.

Contact the recipient by some other means (by phone, for example) and ask them to tell their email admin that it appears that their email system is refusing connections from your email server. Give them the error details shown below. It’s likely that the recipient’s email admin is the only one who can fix this problem.

For Email Admins
No connection could be made because the target computer actively refused it. This usually results from trying to connect to a service that is inactive on the remote host - that is, one with no server application running.

Your domain seems to lack MX records. Also the DNS doesn’t point to your box but still to Digital Ocean. That would explain your other problem, too.

You need to set prodaja.ba’s nameservers to ns1.box.maildelivery.pw and ns2.box.maildelivery.pw, too.

Thanks!
Thanks!

Thanks!

I have a website running on these namservers. And the domain registrar doesn-t support the glue records

As the manual states, glue records are only set on your main domain (maildelivery.pw). Any additional domains do not need them. Just set the dns records.

Before you do so, you should check the other records, like for prodaja.ba and www.prodaja.ba, to set them on your box again (in the admin control panel under System > Custom DNS).
