# Skip mailers while generating Rails 5 app

We can skip adding mailers and its configuration when generating Rails 5 app

We can now
[skip requiring Action Mailer](https://github.com/rails/rails/pull/18288) while
generating Rails 5 app.

```bash

$ rails new my_app --skip-action-mailer

# OR

$ rails new my_app -M

```

This comments out requiring `action_mailer/railtie` in `application.rb`.

It also omits mailer specific configurations such as
`config.action_mailer.raise_delivery_errors` and
`config.action_mailer.perform_caching` in `production/development` and
`config.action_mailer.delivery_method` by default in `test` environment.

```ruby

# application.rb

require "rails"
require "active_model/railtie"
require "active_job/railtie"
require "active_record/railtie"
require "action_controller/railtie"
# require "action_mailer/railtie"
require "action_view/railtie"
require "action_cable/engine"
require "sprockets/railtie"
require "rails/test_unit/railtie"

```

As, we can see `action_mailer/railtie` is commented out.
