Looking at the small print (literally) on that screenshot, it would appear to be the sort of thing that no self-respecting spammer would be without!
The reason that it is so difficult to find an SMTP server host willing to relay your outbound mail is precisely because of spam.
I would never recommend anyone who doesn't know exactly what they are doing to set up an SMTP server - especially on a broadband connection. It is too easy to leave an open relay to be exploited by spambots. Then it will be YOUR smtp server and YOUR domain that is blacklisted.
I'm not having a go at you - just emphasising the problems with SMTP relays.
