Mailer does net send mails in engine

Question

I'm coding a newsletter engine in rails 4 for a simple eCommerce system. For that I write this mailer for my engine at \app\mailers\aecs_newsletter\newsletter_mailer.rb:

module AecsNewsletter
    class NewsletterMailer < ::ActionMailer::Base

        default from: 'newsletter@ecommerce.de'

        def send_newsletter_to_subscribers(subscribers, newsletter)
            subscribers.each do |subscriber|
                @email = subscriber.email
                @newsletter = newsletter
                mail(to: @email, subject: newsletter.subject, template_name: 'newsletter')
            end
        end

    end
end

I inherit from ::ActionMailer::Base to get the mailing configuration of the main application. This configurations works well (tested by the confirmation mails of devise).

But when I execute the function send_newsletter_to_subscribers in a controller of my engine, the function end without an error and without sending a mail.

Here is the log of the method call:

Started GET "/newsletters/admin/1/send_newsletter" for x.x.x.x at 2014-01-28 13:19:47 +0100

[...]
Redirected to http://x.x.x.x:3000/newsletters/admin/1
Completed 302 Found in 547ms (ActiveRecord: 375.0ms)

So the function renders the views, but no mail was sent. I think, that I don't have inherit the mailing configuration right. But in which way I cound use the main app mailer configuration?

Has anyone a solution for my problem? Thanks!

You have not asked it to be delivered. Add .deliver

module AecsNewsletter
    class NewsletterMailer < ::ActionMailer::Base

        default from: 'newsletter@ecommerce.de'

        def send_newsletter_to_subscribers(subscribers, newsletter)
            subscribers.each do |subscriber|
                @email = subscriber.email
                @newsletter = newsletter
                mail(to: @email, subject: newsletter.subject, template_name: 'newsletter').deliver
            end
        end

    end
end
