Overview

This cop disallows adding global helpers to the ‘app/mailers` directory.

The goal is to encourage developers to put new mailer files inside the correct namespace, where they can be more modularly isolated and ownership is clear.

Examples:

# bad
# path: components/my_component/app/mailers/foo.rb
class Foo
  # ...
end

# good
# path: components/my_component/app/mailers/my_component/foo.rb
module MyComponent
  class Foo
    # ...
  end
end
