For reasons I dont fully understand, Microsoft decided some time ago to remove this feature. I suspect mainy because the SMTP server was pretty basic and did not so 'modern authentication'. Plus the cost of adding that in was probably not considered to be appropriate given the usage. SO many networking features have been added to NT the lost over the years.
I have not found a simple smtp server to add into Windows Server that is free - and easy to use. But i have not searched all that hard! You could look here to see if any of the mentioned products would suit your needs: https://forwardemail.net/en/blog/open-source/windows-email-server
I suspect you may be better off spinning up a Linux VM and using something like OpenSMPD (https://github.com/OpenSMTPD). There are loads of servers available depending on your requirement.

- It's been a deprecated feature since WS2012....The writing has been on the wall, and because of the preview you know ahead of GA that it's not going to be there anymore. WS2022 still supports it and will be around for quite a while yet, so it's not like there won't be a supported way as soon as WS2025 is released. But time to start looking at alternatives like linux postfix if you want on-prem still, or using Exchange Onine, Azure Communication Services or SendGrid

An old solution was hMail Server, it's a light app that it's still around with all the features you would need. Check to make sure there no vulnerabilities with the available version.
