I'm back. I'm still working on my ISP to unblock incoming port 25. I may be making some headway with this finally.

I also have a quick question on how I need my settings to be.

under System -> Settings -> Mail Settings I have
Mail Domain: mtnleopolds.com
Mail Hostname: mtnleopolds.com

I'm not exactly sure what these are and if the should be mail.mtnleopolds.com or smtp.mtnleopolds.com or if they are fine as is.
