Resque::Failure::Multiple.configure do |multi|
  # Always stores failure in Redis and writes to log
  multi.classes = Resque::Failure::Redis, Resque::Failure::Logger
  # Production/staging only: also email us a notification
  multi.classes << Resque::Failure::Notifier if Rails.env.production? || Rails.env.staging?
end

When calling super, doesn't that reference Base#save which is an empty method? This code is not storing in Redis for me.

Older versions of Resque stored to Redis form Failure::Base.

Newer versions introduce Failure::Redis and you need to use Failure::Multiple to compose. Let me find an update and post it.

Does this use your ActionMailer SMTP settings? It seems like the rails environment hasn't loaded by this point if you put it in an initializer, but I could be wrong.

It would be nice if there was a way to have this reuse whatever mail settings your app is already using to dry it up.

Ending up using this instead: https://github.com/anandagrawal84/resque_failed_job_mailer

Seemed to work with existing SMTP settings.
