Has anyone used Media Magnet Pro? Need Help!

Hi

I'm having problems sending emails out on the system (Press Releases)
I'm wondering could it be that my emails local SMTP server and port that I do not have right? Maybe it's something else you may know.
Any help would be appreciated.

Thanks,
Brian.

Can you share media magnet pro to me? If yes, thank and I can test whether I can send it out with my smtp server and port
