Development and production configurations for Rails mailer

Question

For deliverability reasons, I installed SPF records and other types of authentication to make sure production emails aren't flagged as spam. The side-effect is that when I run tests from my localhost they don't work. Is there a "Rails Way" to have development vs. production credentials for a mailer? It seems like I could build my own logic based on the Rails.env variable, but I don't want to reinvent the wheel if there is already support for this.

Answer 1

The "Rails way" is to put shared configuration in config/application.rb and environment-specific overrides in config/environments/<env>.rb .

In your case I would put your SPF stuff in config/environments/production.rb .
