Redmine

Hello,

I have a problem with email notification Bitnami Redmine.

I explain: I installed bitnami-redmine 3.1.0 on a Windows Server 2012 R2 virtualized and I would like to configure notification email redmine. So I opened the configuration.yml file in "C: \ Bitnami \ redmine-3.1.0-0 \ apps \ redmine \ htdocs \ config" and I write this inside:

email_delivery:
delivery_method:: smtp
smtp_settings:
address: me@mycompany.com
Port: 25
domain: mycompany.com
authentication:: login
user_name: me@mycompany.com
password: mypassword

I followed this tutorial http://www.redmine.org/projects/redmine/wiki/EmailConfiguration but I still can not.
"Error while sending the email (530-5.5.1 Authentication Required. Learn more at)"

I thank you.
