Error setting up Redmine outgoing email

I am unable to setup email notifications on Redmine 1.0.3. I get following error when I ry sending a test mail:

An error occurred while sending mail (getaddrinfo: The storage control blocks were d开发者_如何学运维estroyed. )

My email.yml is as follows

production:
  delivery_method: :smtp
  smtp_settings:
    tls: true
    enable_starttls_auto: true
    address: "smtp.gmail.com" 
    port: '587'
    domain: "smtp.gmail.com" 
    authentication: :plain
    user_name: mymail@mydomain.com
    password: PASSWORD

Will appreciate any help on this.
