Email preview in production in rails 4

Hello,

I am using rails 4.1.1 and ActionMailer::Preview. In development
environment everything is working excellent.

But in production environment the preview routes are not accessible. I
store the previews in test/mailers/previews/
Is is possible to enable them for production?

I have also asked Email preview in production in rails 4 · Issue #82 · basecamp/mail_view · GitHub (I
used
this gem in rails 3. As far as I know it now merged in rails 4 and is
used
for mail previews)

Thanks!
