Redmine

I want redmine to be able to send notification emails. I renamed the example file to email.yml and poked around a bit.
But I cant seem to get the "send test email" to work. I get:
"An error occurred while sending mail (No connection could be made because the target machine actively refused it. - connect(2))"

The first search turned up this: http://www.redmine.org/boards/2/topics/show/2607
But doesnt that config look wierd? Isnt most of the settings commented out?

I also found this bug: http://www.redmine.org/issues/show/2212
Could I be affected?

Strange thing is, my searches just turns up people asking for help, no actual documentation about the config files. Or are they hidden somewhere and not included in the searches?

I tried to run the command, but my redmine is hosted on a windows box. RAILS_ENV I guess is an enviorment variable, but I couldnt set it with that command. But running "ruby script\about" at least gave output. Although it seems to default to development env. But the version numbers are still there.
