Send mail over smtp server in redmine app hosted on openshift - openshift

Question

I want to send mails in my deployed redmine application, which I host on openshift. I used this tutorial to set everything up: link to tutorial
To send an email via the google smtp server I changed my configuration.yml file like that:
# = Redmine configuration file
#
# Each environment has it's own configuration options. If you are only
# running in production, only the production block needs to be configured.
# Environment specific configuration options override the default ones.
#
# Note that this file needs to be a valid YAML file.
# DO NOT USE TABS! Use 2 spaces instead of tabs for identation.
#
# == Outgoing email settings (email_delivery setting)
#
# === Common configurations
#
# ==== Sendmail command
#
# production:
# email_delivery:
# delivery_method: :sendmail
#
# ==== Simple SMTP server at localhost
#
# production:
# email_delivery:
# delivery_method: :smtp
# smtp_settings:
# address: "localhost"
# port: 25
#
# ==== SMTP server at example.com using LOGIN authentication and checking HELO for foo.com
#
# production:
# email_delivery:
# delivery_method: :smtp
# smtp_settings:
# address: "example.com"
# port: 25
# authentication: :login
# domain: 'foo.com'
# user_name: 'myaccount'
# password: 'password'
#
# ==== SMTP server at example.com using PLAIN authentication
#
# production:
# email_delivery:
# delivery_method: :smtp
# smtp_settings:
# address: "example.com"
# port: 25
# authentication: :plain
# domain: 'example.com'
# user_name: 'myaccount'
# password: 'password'
#
# ==== SMTP server at using TLS (GMail)
#
# This might require some additional configuration. See the guides at:
# http://www.redmine.org/projects/redmine/wiki/EmailConfiguration
#
# 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: "your_email#gmail.com"
# password: "your_password"
#

#
# On Windows + JRuby 1.6.2, path which contains spaces does not work.
# For example, "C:\Program Files\TortoiseHg\hg.exe".
# If you want to this feature, you need to install to the path which does not contains spaces.

email_delivery:
delivery_method: :smtp
smtp_settings:
enable_starttls_auto: true
address: "smtp.gmail.com"
port: 587
domain: "smtp.gmail.com"
authentication: :plain
user_name: "test#gmail.com"
password: "testword"
However, when I am getting in the running application under mail in the admin configurations:
The SMTP server is not configured and notifications are disabled.
Make the settings for your SMTP server in config / configuration.yml before and restart the application.
Any suggestions how to fix that?
I appreciate your answer!
UPDATE
Using the below described method(s) I get the following error, when sending a test email:

Answer 1

The obvious fix is to edit the configuration.yml file in your local repo but you'll soon find out that its in your .gitignore file (for security reasons), so there are two options. I was able to get it working with both options but I would recommend using the first one if you can. The only reason you would want the second one to be used is simply because you want to keep your configuration.yml out of your git repo.
The first option isn't really less secure since its not really storing any important information in plain text. It uses the environment variables we'll set with rhc to pull the correct information.
Edit:
Since there seems to be a problem with redmine taking environment variables in their configuration files (and I tried this solution with no success). The only way I was able to successfully send email was by doing the following:
Remove configuration.yml from your .gitignore file on your local machine
vim .gitignore
Copy the "config/configuration.yml.example > config/configuration.yml" by doing:
cp config/configuration.yml.example configuration.yml
Then use vim to edit the file
vim config/configuration.yml
Append the following:
production:
email_delivery:
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: "my-email-account#gmail.com"
password: passwordnotinquotes
Save and exit
:wq
exit the ssh session and run:
rhc app restart <appname>
Go to the administration settings and configure your email
Be advised. This will store the email credentials in plain text, however this seems to be standard practice for redmine configuration according to their docs.
