Rails ActionMailer with multiple SMTP servers

Question

I have a need to use two different smtp servers in a Rails application. It appears that the way ActionMailer is constructed, it is not possible to have different smtp_settin

Here's another solution, which, while it looks ridiculous, I think is a little bit cleaner and easier to reuse in different AM::Base classes:

    module FTTUtilities
      module ActionMailer
        module ClassMethods
          def smtp_settings
            dict = YAML.load_file(RAILS_ROOT + "/config/custom_mailers.yml")[self.name.underscore]
            @custom_smtp_settings ||= HashWithIndifferentAccess.new(dict)
          end
        end

        module InstanceMethods
          def smtp_settings
            self.class.smtp_settings
          end
        end
      end
    end

example Mailer:

    class CustomMailer < ActionMailer::Base
        extend FTTUtilites::ActionMailer::ClassMethods
        include FTTUtilites::ActionMailer::InstanceMethods
    end
