Redmine

I resolved the notification error by editing apps\redmine\htdocs\config\configuration.yml like below:

# default configuration options for all environments
default:
  # Outgoing emails configuration (see examples above)
  email_delivery:
    delivery_method: :smtp
    smtp_settings:
      # arguments: "-i"      
      address: "10.192.1.1" 
      port: 25
      domain: "xxx.com.cn" 
      authentication: :login
      user_name: "user1" 
      password: "123456" 
      enable_starttls_auto: true

Another problem is :
i can't find redmine logs,the apps\redmine\htdocs\log\production.log does not help very much!
