Hello, I want to work my way thru understanding this product, starting from almost no knowledge of the deeper issues with mail servers. I have a Dell server running Windows Server 2024 and I have a wildcard SSL certificate. I have a fixed IP address and I can control my ports. Many years ago I downloaded SM and hacked it to run on Windows 7 in a similar environment, but a TLS change obviated this and I lost interest. Anyway, I will pay someone to walk me thru installing SM and demonstrating it can send and receive from Gmail and from Outlook/Hotmail. DNS needs to be included.
