Redmine

I have downloaded BITNAMI stack to set up Redmine on a new server. Everything went OK until I started to set up email configuration. In the email.yml settings, I have specified as per the instructions but redmine not started after that. Got error trace as below: I used the authentication as :login, :none, login (without colon), none (without colon) but I get the same error.

When I used 0.7, I used to do it in environment.rb, it works perfectly.

Please advise.
