Problem PHP Mail Function Alma Linux 8

Test done: AlmaLinux 8 + CWP Pro
Installation of s-nail in console then reboot of the server.

The problem remains the same no mail from the php scripts and the logs
are normal without errors.

Do I need to make a special configuration or adjustment to php.ini?

You have to use an email address thats on the server or it will balk.  IOW no gmail
