Iredmail server not accepting emails

I recently created an iredmail email server through ubuntu 20.4. It was a fresh server. I am very new to the server world.

None of my emails are being delivered to the web based iredmail inbox. I am able to send emails to gmail with iredmail.

The response i get on gmail when trying to send an email to iredmail is - server is refusing email. I have been trying to figure this out for hours. I have had no luck. The DNS is configured correctly according to the dns tests on the web.

I have no idea what to do from here. if someone could give me some wisdom that would be greatly appreciated.

Thank you
