Answer 1

apneadiving is correct, adding to his solution, other folks downloading your code, may won't figure out quickly how to generate this yml, so you'll need to give them a hint, by having the following structure:

config
  |
  |--- environment.rb
  |--- mail_settings.yml
  |--- main_settings.yml.example

Having the file 'mail_settings.yml' contains your sensitive information and NOT included in the repo, and have 'main_settings.yml.example' included in your repo, and having the same structure as 'mail_settings.yml'.

And to be more helpful, provide a section in you README file, describing that people need to copy the mail_settings.yml.example file to mail_settings.yml and enhance it's content.
