Funny. They charge ten bucks for something that is based on free, open-source software (postfix). You can get this for free. Postfix only has to be activated in OS X Panther, and even in Jaguar it's fairly easy to install.

I have described the process (5 to 10 minutes, honestly!) on my web site:

I wish the makers of this software would spend their time on something more original...
