Gmail configuration for redmine on Ubuntu

To install redmine, use

sudo apt-get install redmine

1. In the redmine folder /usr/share/redmine/config, copy configuration.yml.example to configuration.yml
2. Edit the configuration.yml file to add the end of the file (Note the indentations, spaces before each line, do matter)

   production:
      email_delivery:
        delivery_method: :smtp
        smtp_settings:
          enable_starttls_auto: true
          address: "smtp.gmail.com"
          port: 587
          domain: "smtp.gmail.com" # 'your.domain.com' for GoogleApps
          authentication: :plain
          user_name: "redmine@psychstat.org"
          password: "xxxxxxxxx"

To automatically fetch emails every 5 minutes, use a cron job. Note to create redmineread and redineerror label in gmail first. If your password is complex enough, remember to quote them.
