I tried all of that, however when I turned SMTP off, then UNA started sending confirmation emails and other emails, on its own, in the same way Wordpress does. I think my host wants PHP mail instead of the STMP app method. I assume UNA's default mailer is PHP mail? All of my DNS records looked correct, and my email box works with my domain, hence I suppose the host wanted to see something specific in terms of a site emailer? I still gives me a headache to think about it, but I have things working now and if anyone has this same problem then try to use the UNA built in emailer.

"I assume UNA's default mailer is PHP mail?" YES
As email volume and requirements grow, UNA CMS can scale by using one of the following approaches:
- Built-in UNA CMS PHP mail service – suitable for testing, development, or low-volume traffic.
- External mail server – the CMS connects via authenticated SMTP to a reliable mail server for medium-volume traffic.
- Dedicated SMTP service from a provider – for high-volume or critical emails, a scalable SMTP service ensures optimal deliverability, reputation management, and reliability.
- Alternatively, if your organization has the expertise, it can build and manage its own SMTP infrastructure to fully control email delivery, scalability, and monitoring.
An SMTP server is straightforward to use, and its main advantage is that it connects directly to your email service. It works very well as long as it is installed and configured correctly. For critical or high-volume emails, an external SMTP server is safer and more efficient than sending directly from your CMS server, as almost any mail provider offers SMTP functionality. However, for true scalability, a dedicated SMTP service is required. The built-in mail service in UNA CMS is intended primarily for testing environments, development, or low-volume email traffic, as its capacity depends on the server’s infrastructure and resources you have.
