So using Microsoft Outlook really opens the world to spam and open relay abuse?
Hey, you're preaching to the converted here in the linux forums. MS Outlook also contributes to world hunger and acne.
No, what they're saying is that it just requires some specialized setup to make it work with your mailserver. So you have to find someone that knows or is willing to do that setup. The alternative of running an open relay should not be an alternative. I wasn't even aware that people did that.
